A strong trailer-ramp hinge should match the existing mounting area, support the gate’s load, and suit the way you maintain it; that makes these weld-on options useful for trailer owners replacing worn hardware or building a ramp door. This lineup includes several 10-inch ramp-specific sets, greaseable designs, and shorter barrel hinges with stated capacity ratings. The choices are not interchangeable: some list a 900-pound capacity, while others give dimensions or pack size without a rated load.
Check the hinge length and installation style against your trailer before choosing, and verify that the stated capacity applies to your full hinge arrangement. The rankings favor direct ramp-door fit and useful specifications, while noting where a product is better suited to a general gate than a trailer repair.
SPARKWHIZ 10 Ramp Hinges lead as a versatile choice for trailer ramp doors: the listing specifies a 4–10-inch range, heavy steel construction, greaseability, weld-on installation, and a four-hinge pack. Those details make them a practical match for buyers seeking ramp-specific hardware rather than a general gate hinge. If you need a precise 10-inch, 1-inch-wide hinge with a stated steel gauge, enenfeifei Trailer Hinges are a close alternative; check your existing setup before ordering either option.

Detailed Reviews: Best Hinges For Trailer Ramp

#1 · Best Overall
1. SPARKWHIZ 10" Ramp Hinges
- Dimensions: 10"L x 10"W
- Material: Steel
- Dimensions L x W: 10"L x 10"W
Best for: Greasable ramp-gate weld-on set.
Why it ranks #1: The four-hinge set is made for 4–10-inch ramp doors and combines heavy steel, weld-on installation, and greaseability for direct trailer use.
A greaseable design pairs with heavy steel construction to give this four-hinge SPARKWHIZ set a maintenance point for frequently swung trailer gates. Its stated suitability for 4- to 10-inch hinges and weld-on installation makes it relevant to ramp-gate projects where the mounting plan calls for welding rather than bolt-on hardware.
The four-piece pack gives installers multiple hinges for a ramp or gate project, while the weld-on construction supports a direct welded attachment. Greaseability provides a way to lubricate the hinge after installation, and the heavy steel material is specified as corrosion resistant. SPARKWHIZ lists the hinges for trailer ramp gates and other hinge applications, so the set can serve more than one type of welded gate project. Check the stated 4- to 10-inch suitability against your installation.
- Four hinges in the pack
- Greasable design
- Heavy steel construction
- Listed as corrosion resistant
- Installation requires welding rather than bolt-on mounting.
Skip it if you need a stated 900-pound capacity; SANKINS model a9c32011-f89a-47af-a0a6-a93258caf5a8 lists that rating.
Choose this set if you need four greasable steel hinges for a welded trailer ramp gate and value corrosion resistance. Its listed 4- to 10-inch suitability is a key fit consideration; the installation itself requires welding.

- Dimensions: 10"L x 1"W
- Material: Steel
- Dimensions L x W: 10"L x 1"W
Best for: Four-piece 9-gauge ramp hinges.
Why it ranks #2: Four 1-by-10-inch weld-on hinges include grease fittings and specify 9-gauge steel, a 7/16-inch pin, and a raised center portion.
A specified 9-gauge steel construction sets these enenfeifei hinges apart for buyers planning a four-piece, 10-inch ramp-door installation. Each weld-on hinge includes an integrated grease fitting and a raised center portion with steel wrap, combining a stated material gauge with lubrication access for ongoing use.
The four-hinge quantity supports a multi-point ramp-door layout, and the 10-inch length identifies the size for installation planning. Integrated grease fittings give a maintenance point after welding, while the raised center portion with steel wrap describes the joint construction. The 9-gauge steel specification and 7/16-inch pin diameter offer additional details for assessing the hardware. These hinges have a raw-steel finish, so buyers should account for that surface when planning an outdoor trailer installation.
- Four hinges included
- 10-inch length
- 9-gauge steel specified
- Integrated grease fitting
- Raw-steel finish has no listed corrosion-resistant coating.
Skip it if you need hinges with a stated 900-pound capacity; Pixplex model 5fd926e9-feaa-4b28-a5a6-3cb5b6d5fb32 specifies that rating.
Choose this set for a welded trailer ramp door needing four 10-inch hinges with grease fittings and a stated steel gauge. Its raw-steel finish and 7/16-inch pin diameter are relevant considerations for outdoor care and installation layout.

#3 · Best Warranty
3. TOPICK 10" Ramp Hinges
- Dimensions: 10"L x 10"W
- Material: Iron
- Dimensions L x W: 10"L x 10"W
Best for: Four-piece greasable ramp set.
Why it ranks #3: This four-piece weld-on set is sized for 4–10-inch ramp doors or gates and lists iron construction plus a one-year manufacturer warranty.
A four-hinge pack with greaseable construction makes TOPICK a useful option for ramp and gate installations that need lubrication after welding. The hinges are specified for 4- to 10-inch ramp doors or gates, and their direct weld-on mounting targets a secure attachment to trailer frames without relying on bolt-on replacements.
The four-piece pack can cover a multi-hinge ramp installation, while the stated 4- to 10-inch range helps narrow the intended door or gate size. TOPICK describes the hinges as welding directly to trailer frames, giving installers a mounting approach for projects already set up for welding. Greasability supports lubrication after installation, and the iron construction is specified for this hinge set. Buyers should plan for welded mounting and check the range against their ramp-door setup.
- Four hinges in the pack
- Greasable design
- Specified for 4- to 10-inch ramp doors or gates
- Direct weld-on mounting
- Requires welding and does not offer a bolt-on mounting method.
Skip it if you need a stated load capacity; SANKINS model a9c32011-f89a-47af-a0a6-a93258caf5a8 lists a 900-pound rating.
TOPICK suits buyers installing four greasable hinges on a trailer ramp or gate within the stated 4- to 10-inch range. It is a weld-on choice, so it does not suit a project that calls for bolt-on hardware.

4. MGWILL 10" Ramp Hinges
- Dimensions: 3.75"L
- Material: Steel
- Dimensions L x W: 3.75"L
Best for: Ten-inch greaseable ramp hinges.
Why it ranks #4: Three 10-by-1-inch raw-steel trailer ramp hinges have integrated grease fittings, a 7/16-inch pin, and a raised center with steel wrap.
A raised center portion with a steel wrap distinguishes MGWILL’s 10-inch ramp-door hinges, while integrated grease fittings provide a lubrication point after installation. This three-piece raw-steel set is specifically listed for weld-on utility trailer ramp doors, with a 7/16-inch pin diameter and approximately 3-3/4-inch center shank.
The 10-inch length and straight weld-on format suit ramp-door installations planned around that hinge size. Integrated grease fittings support maintenance after welding, while the raised center portion and steel wrap describe the hinge’s construction around the joint. The approximately 3-3/4-inch center shank and 7/16-inch pin diameter give installers measurements to consider during layout. Three hinges are included, and the raw-steel finish is a factor for buyers planning an outdoor installation and its surface care.
- Three 10-inch hinges included
- Integrated grease fittings
- Raised center portion with steel wrap
- 7/16-inch pin diameter specified
- Raw-steel finish has no listed corrosion-resistant coating.
Skip it if you need four 10-inch hinges rather than three; enenfeifei model 0680140858169 lists a four-piece set.
MGWILL suits buyers welding 10-inch greasable hinges onto a utility trailer ramp door and who can use a three-piece pack. Its raw-steel finish and stated pin and shank dimensions matter for surface care and layout.

5. Otoolling 10" Hinges
- Dimensions: 0.39"L x 0.39"W
- Material: Alloy Steel
- Dimensions L x W: 0.39"L x 0.39"W
Best for: Multi-hinge ramp-door projects.
Why it ranks #5: The six-piece set provides 1-by-10-inch trailer door hinges made from alloy steel, a useful format for multi-hinge installations or spares.
Six 1-by-10-inch hinges make the Otoolling set a practical match for multi-part trailer-door work or keeping spares on hand. The raw-steel hinges are weld-on and are described as able to withstand frequent opening and closing and heavy impact, giving repair and assembly projects a larger matching set.
The six-piece quantity can cover a multi-hinge installation or leave spare hinges for later repairs, reducing the need to source another matching set mid-project. Each hinge is specified as 1 by 10 inches and made from raw steel, with weld-on mounting for a welded trailer frame. The product description says the hinges resist deformation and handle repeated opening, closing, and heavy impact. Because the surface is raw steel, buyers should account for finish needs in their installation environment.
- Six hinges included
- 1-by-10-inch size
- Weld-on mounting
- Described for frequent operation and heavy impact
- Raw steel surface has no listed corrosion-resistant coating.
Skip it if you need grease fittings for ongoing lubrication; HOHNNYREET model 6 inch Heavy Duty Weld on Hinges specifies them.
This set fits buyers repairing or assembling a trailer ramp door who need six matching 1-by-10-inch weld-on hinges. Its raw-steel surface and lack of a listed grease fitting are relevant boundaries for outdoor maintenance plans.

#6 · Greaseable Short Hinge
6. HOHNNYREET 6" Hinges
- Dimensions: 6"L x 0.7"W
- Material: Carbon Steel
- Dimensions L x W: 6"L x 0.7"W
Best for: Lubrication-ready utility ramps.
Why it ranks #6: Four 6-inch carbon-steel weld-on hinges include grease fittings, suiting buyers who need a shorter hinge and ongoing lubrication access.
Integrated grease fittings are the defining feature of these four 6-inch HOHNNYREET hinges, giving installers a direct way to lubricate the joints after welding. Carbon steel construction and the listed uses—trailer ramps, utility trailers, metal gates, and BBQ smokers—make the set relevant to several welded swing-hinge projects.
The grease fittings let users add lubrication after installation, a useful maintenance step for hinges that need smooth swinging. Four hinges are included, giving buyers a coordinated set for a multi-hinge project. Their 6-inch length and carbon-steel construction identify the hardware, while weld-on mounting suits metal frames that can be welded. The product lists trailer ramps and utility trailers among its applications, but does not state a load capacity, so buyers needing a rated limit should use a product with a stated figure.
- Four hinges included
- Integrated grease fittings
- 6-inch hinge length
- Carbon steel construction
- No load capacity is stated for assessing a rated weight requirement.
Skip it if you require a stated 900-pound capacity; Letowe model Letowe lists that rating for its 7-inch hinges.
These suit buyers who want four greaseable 6-inch weld-on hinges for a trailer ramp or utility trailer. Their stated size and lack of a listed load rating are important boundaries when matching the set to a specific gate.

7. MOUNTAIN_ARK Weldable Hinges
- Dimensions: 4.57"L x 4.17"W
- Material: Low Carbon Steel
- Dimensions L x W: 4.57"L x 4.17"W
Best for: Wide-opening removable-pin hinges.
Why it ranks #7: These four low-carbon-steel weldable hinges measure 4-1/2 by 4-1/4 inches and list a 440-pound maximum load per pair.
A maximum 285-degree rotation angle gives these MOUNTAIN_ARK hinges a wide opening range for a metal trailer ramp gate. Their removable pin adds a separable hinge option, while the four-piece pack and 440-pound-per-pair load specification give buyers concrete details for planning the installation and its supported load.
The 285-degree maximum rotation can accommodate a broad swing path where a ramp gate needs to open widely. Removable pins provide a way to separate the hinge components, which can help with gate handling during installation or later work. The low-carbon-steel hinges measure 4-1/2 by 4-1/4 inches and are 3/16 inch thick; the stated 440-pound maximum applies per pair. The plain finish is a practical consideration when choosing treatment for the installed steel.
- Maximum rotation of 285 degrees
- Removable pin
- Four hinges included
- 440-pound maximum load per pair
- Plain finish does not provide a listed corrosion-resistant coating.
Skip it if you need a coated 7-inch hinge with a 900-pound capacity; Pixplex model 5fd926e9-feaa-4b28-a5a6-3cb5b6d5fb32 lists both.
Pick these for a welded metal ramp gate where wide rotation and a removable pin matter. The 440-pound rating is per pair, not the four-piece pack, and the plain finish makes surface protection worth considering.

8. SANKINS 7-Inch Hinges
- Dimensions: 7"L x 7"W
- Material: Steel
- Dimensions L x W: 7"L x 7"W
Best for: Rated heavy swinging gates.
Why it ranks #8: The two 7-inch steel weld-on hinges list a 900-pound capacity and a black matte coating, but are described broadly as gate hinges.
A stated 900-pound capacity is the defining specification of these 7-inch SANKINS hinges, giving buyers a clear load figure for a heavy swinging gate or trailer ramp. Their solid steel construction and thickened mounting plate also address support at the welded joint, while the black matte coating suits outdoor use.
SANKINS specifies a 900-pound capacity for the 7-inch steel hinges, which helps buyers assess them against a gate's load requirement. The thickened mounting plate is intended to stabilize the gate and help resist sagging or warping. A black matte coating provides corrosion resistance for outdoor placement. This two-piece set is weld-on, so it suits projects where welding is part of the mounting workflow; its capacity and 7-inch size should guide selection for the intended gate.
- Stated 900-pound capacity
- 7-inch solid steel hinges
- Thickened mounting plate
- Corrosion-resistant matte coating
- The two-pack provides only two hinges for the installation.
Skip it if you need four 10-inch ramp-door hinges; TOPICK model WTH-TP-01 comes as a set of four.
This pair suits buyers fitting a 7-inch weld-on hinge to a heavy swinging gate or trailer ramp and needing a stated 900-pound capacity. Plan around the two-hinge pack and confirm the gate layout can use this size.

9. Pixplex 7-Inch Hinges
- Dimensions: 7"L x 1.25"W
- Material: steel
- Dimensions L x W: 7"L x 1.25"W
Best for: Coated high-capacity gate pair.
Why it ranks #9: This two-piece, 7-inch steel barrel-hinge set lists a 900-pound capacity and a coated finish for outdoor use, though its focus is general gates.
A stated 900-pound capacity paired with a matte black corrosion-resistant coating defines Pixplex’s two 7-inch barrel hinges. The thick cold-roll steel construction and weld-on mounting target heavy swing gates and trailer ramps, while the specified 1.25-inch barrel and back-plate width help buyers assess the hardware against their installation.
The 900-pound capacity gives a specific load figure for buyers comparing this pair with a gate’s requirements. Its 7-inch length, 1.25-inch barrel diameter, and 1.25-inch back-plate width provide useful dimensions for planning the weld-on placement. Thick cold-roll steel supplies the hinge material, while the matte black coating is described as corrosion resistant for indoor and outdoor use. The two-hinge pack suits a paired installation, but does not supply a larger multi-hinge set.
- Stated 900-pound capacity
- Matte black corrosion-resistant coating
- Thick cold-roll steel
- Specified barrel and back-plate dimensions
- Only two hinges are included in the pack.
Skip it if you need four hinges with a removable pin and wide swing; MOUNTAIN_ARK model P-CF1218 HEYE12 specifies both.
Choose Pixplex when a two-hinge, 7-inch welded pair with a stated 900-pound capacity and coated finish suits the gate. Check the specified barrel and back-plate dimensions against the weld location before installation.

10. Letowe 7-Inch Hinges
- Dimensions: 1.25"L x 7"W
- Material: Cast Iron, Iron
- Dimensions L x W: 1.25"L x 7"W
Best for: Greaseable rated gate hinges.
Why it ranks #10: The two 7-inch weld-on hinges list a 900-pound capacity and grease fittings, but offer less specific ramp-door sizing than the higher-ranked options.
A 900-pound capacity and grease fitting combine in Letowe’s 7-inch weld-on barrel hinges, pairing a stated load figure with a maintenance feature. The extra-thick back plates are specified to support secure welding, making this two-piece set relevant to trailer ramps and other heavy swing gates.
The 7-inch hinges carry a stated 900-pound capacity, helping buyers evaluate them against a gate’s load needs. A grease fitting supports lubrication for smoother operation, while the extra-thick back plates are described as helping create a secure weld-on installation. The black iron barrel style is listed for trailer ramps, swing doors, and metal driveway gates. Letowe also describes 5-inch and 7-inch sizes, but this two-piece listing identifies the 7-inch option, so size selection matters.
- Stated 900-pound capacity
- Grease fitting for lubrication
- Extra-thick back plates
- Weld-on installation
- The pack includes only two hinges.
Skip it if you need six 1-by-10-inch ramp-door hinges; Otoolling model HUU-Otoolling-1374 supplies a six-piece set.
Letowe fits buyers seeking a greaseable 7-inch pair for a welded trailer ramp or swing gate, with a stated 900-pound capacity. The two-hinge quantity and specified size should match the gate’s layout and installation plan.

View on AmazonAvoid a hinge-size mismatch
A hinge’s listed length alone does not establish that it will fit your trailer’s mounting area. The listings span 4-1/2-by-4-1/4-inch weldable hinges, 6-inch hinges, 7-inch barrel styles, and 10-inch ramp-door designs; some 10-inch sets also specify a 1-inch width. Before replacing hardware, measure the hinge leaves or barrel, pin location, mounting clearance, and the space available for the weld.
Compare the old hinge’s open and closed positions with the replacement’s geometry, since a hinge that fits the frame may still interfere with the ramp or fail to let it swing as intended. The SPARKWHIZ listing describes suitability for 4–10-inch doors, but that range does not replace checking the actual hinge footprint and clearance.
Product dimensions and naming can describe different parts of a hinge, so confirm what each measurement refers to before treating two sizes as equivalent.
Why load ratings need context
A stated capacity is useful only when you know what it describes and how the hinges will be installed. SANKINS and Pixplex list 900-pound capacities for their 7-inch hinge sets, while MOUNTAIN_ARK specifies 440 pounds per pair; those figures use different descriptions and should not be compared as if they were a shared test result. Several ramp-specific 10-inch products provide no numeric capacity in the supplied specifications, so their heavy-duty descriptions are not a substitute for a rated load.
Trailer-ramp weight, how it is distributed across hinges, and the forces of opening and closing all matter to the finished installation. Treat capacity claims as product-specific, not as a guarantee for an entire ramp assembly.
If the ramp is heavy or sees frequent use, confirm the hinge maker’s rating and installation requirements for your exact application before welding.
How to Choose Trailer Ramp Hinges
Hinge length and fit
Look for a hinge length and footprint that match the existing mounting area and ramp movement. This selection ranges from 4-1/2-by-4-1/4-inch MOUNTAIN_ARK hinges to 6-inch HOHNNYREET and 7-inch SANKINS, Pixplex, and Letowe models. The ramp-specific choices include 10-inch hinges from SPARKWHIZ, TOPICK, MGWILL, and enenfeifei; enenfeifei also lists a 1-inch width.
SPARKWHIZ describes suitability for 4–10-inch doors, while TOPICK gives the same range for ramp doors or gates. A short hinge may suit a compact mounting area, while a 10-inch style may better match a long ramp-door layout.
Measure the old hardware and available clearance rather than choosing by length alone.
Capacity and load information
Look for a capacity that fits your ramp and note exactly how the manufacturer states the rating. SANKINS and Pixplex list a 900-pound capacity for their 7-inch hinge sets; MOUNTAIN_ARK lists 440 pounds per pair. Letowe also lists 900 pounds for its 7-inch hinges.
The ramp-specific 10-inch products generally do not provide a numeric capacity in the supplied data, so their heavy-duty wording does not allow a direct rating comparison. Buyers prioritizing a stated figure can start with a capacity-listed hinge, while those replacing a 10-inch ramp-door assembly may favor an exact-size ramp hinge and seek application-specific load guidance.
Do not assume a pair rating, set rating, or gate rating represents the same thing.
Lubrication and pack format
Check whether the hinge has a grease fitting and whether the set contains enough pieces for your layout. Greaseable options include the four-piece SPARKWHIZ and TOPICK sets, three-piece MGWILL set, and HOHNNYREET’s four 6-inch hinges. enenfeifei lists grease fittings on a four-piece, 9-gauge set; Letowe also describes grease fittings.
Otoolling supplies six hinges, while several other choices come in packs of two or four. A greaseable design suits buyers who want a way to lubricate the hinge after installation, but it still needs compatible access once welded in place.
A larger pack can help when several hinges are required or spares are desired; first determine the number and position needed for the specific ramp.
Which Trailer Ramp Hinge Should You Choose?
For a general-purpose, ramp-specific replacement, choose SPARKWHIZ 10 Ramp Hinges: its four-piece set is described for 4–10-inch ramp doors and is both weld-on and greasable. For a precisely described 10-inch hinge with gauge and pin details, consider enenfeifei Trailer Hinges, which lists 9-gauge steel and a 7/16-inch pin. Choose TOPICK 10 Ramp Hinges if its 4–10-inch fit range and four-piece pack suit your repair.
If you need six 10-inch hinges, Otoolling 10 Hinges offers that pack format. For a shorter, greaseable option, HOHNNYREET 6 Hinges list four carbon-steel hinges with grease fittings.
Buyers focused on a numeric capacity can compare the 900-pound-listed gate styles, but should verify that the rating applies to their ramp and installation.

Frequently Asked Questions
How should I measure a trailer ramp before replacing its hinges?
Measure the existing hinge length and width, then check how it mounts and where its pin sits relative to the ramp and frame. Compare those dimensions with the replacement listing and confirm the hinge can align with your existing installation. Do not assume a listed length alone guarantees a compatible fit.
How many hinges should a trailer ramp use, and how should they be spaced?
Use the number and placement required to support your ramp and match its existing mounting points; the product packs alone do not establish a suitable count. Check the ramp and frame for attachment locations, distribute hinges along the supported edge, and verify alignment and secure mounting before putting the ramp into service.
What welding and lubrication steps help prevent a replacement hinge from binding or wearing prematurely?
Before welding, align the hinge leaves and pin so the hinge moves freely through its range; avoid welding it in a twisted or misaligned position. Follow appropriate welding practices for the materials and installation. For a greasable hinge, use its grease fitting as intended and check operation after installation to catch binding early.
How can I check whether a hinge’s stated capacity suits my trailer ramp?
Treat a capacity printed for a gate-style hinge as a listing detail, not proof that it supports your ramp installation. Check whether the rating applies to your ramp, mounting arrangement, and load, and confirm the hinge material and attachment method suit the job. Seek qualified guidance if those details are uncertain.
When should I choose a greasable hinge over a plain weld-on hinge?
Choose a greasable option when you want a hinge with a grease fitting or listed greaseability for routine lubrication. The supplied listings include several such ramp-specific options, while others are described mainly as weld-on hinges. Compare fit, pack quantity, and installation details first; the title alone does not establish maintenance requirements.
Final Words
Start by measuring the existing hinge and checking its mounting layout, then compare the listed dimensions and pack quantity with your repair. SPARKWHIZ is the versatile ramp-specific pick when its 4–10-inch range, four-piece pack, weld-on design, and greaseability fit your setup. Consider enenfeifei for its stated 10-inch size and gauge details, or another listed option when its length or pack format better matches your needs.
Verify any capacity rating for your ramp and installation.
