Best Fifth Wheel Plate For Semi: 10 Plates Compared

#1 · Best Overall

1. Mytee 36-Inch Disc

• Weight: 7.5 lb
• Material: High Density Polyethylene (HDPE)

Best for: Large-diameter truck setups.

Why it ranks #1: Its 36-inch, 5 mm HDPE disc is the largest listed truck-style option, and the included zinc-coated steel clip adds retention hardware.

A 36-inch HDPE disc gives this Mytee Products plate a larger contact area than the smaller listed plates, while its smooth surface provides a low-friction interface. The included zinc-coated steel retention clip helps keep the plate in place, and the slip-on design avoids applying fifth-wheel grease during routine coupling.

At 5 mm thick and 36 inches in outer diameter, this disc is the largest-diameter option in the supplied lineup, so it suits buyers seeking a broad plate for a truck, trailer, RV, or camper. Its HDPE material and smooth surface provide the stated friction-protection function, while the slip-on format keeps installation straightforward. The zinc-coated steel retention clip is included to help retain the disc. At 7.5 pounds, it is a substantial plate to handle and store.

Skip it if you need a compact 10-inch RV plate; scottchen PRO TCD-01 is listed for a standard 2-7/8-inch pin.

Truck and trailer owners seeking a 36-inch HDPE friction-protection plate may value the smooth surface and included retention clip. Check that this large diameter suits the fifth-wheel setup before choosing it.

#2 · Best Clip Included

2. Buyers FWD32

• Weight: 5.1 lb
• Material: Polymer
• Compatible with Vehicle Type: Trailer, Truck

Best for: Truck fleet grease alternatives.

Why it ranks #2: This 32-inch polymer lube disc is listed for trucks and trailers and includes a steel retention clip for a practical truck-focused setup.

The Buyers Products FWD32 combines a 32-inch self-lubricating polymer disc with a steel retention clip, giving truck and trailer operators a grease-free plate with a listed retaining component. Its stated purpose is to reduce coupling mess and friction-related wear between the fifth wheel and trailer.

The 32-inch diameter and truck-and-trailer compatibility make the FWD32 relevant to buyers seeking a full-size plate for towing equipment. Buyers Products describes its polymer surface as self-lubricating, which removes the need for messy fifth-wheel grease during coupling and uncoupling. The product description also connects the polymer construction with reduced friction and wear between the plate and trailer. A steel retention clip is included, providing a listed component to help hold the disc in place during use.

Skip it if you need a 12-inch RV plate with self-cleaning grooves; CURT 16722 lists that size and feature.

Truck and trailer operators wanting a 32-inch polymer disc, included steel clip, and less grease handling are the clearest audience. The fixed 32-inch diameter is the key fit boundary for this FWD32.

#3 · Polyurethane Option

3. World American 32-Inch Disc

• Weight: 6 lb
• Compatible with Vehicle Type: Truck

Best for: 32-inch replacement-disc shoppers.

Why it ranks #3: The 32-inch polyurethane disc includes a retainer and is specified as compatible with trucks, making its listed use a close match for semi buyers.

A 32-inch polyurethane disc paired with an included retainer gives the World American option a defined replacement setup for truck applications. Its listed size suits buyers seeking a full-size fifth-wheel lubrication disc, while the retainer is part of the package rather than a separately listed accessory.

The 32-inch size and truck compatibility make this a straightforward candidate for buyers replacing a similarly sized fifth-wheel disc. The included disc retainer supports the installation by providing a listed retaining component alongside the plate. Its polyurethane construction distinguishes it from the listed polymer and HDPE alternatives, although the supplied information does not specify thickness or surface treatment. At 6 pounds, it is a substantial component to handle when installing or keeping a spare on hand.

Skip it if you need a 10-inch plate for a standard 2-7/8-inch pin; scottchen PRO TCD-01 lists that fit.

Choose this World American disc if your truck application calls for a 32-inch polyurethane plate and included retainer. Its supplied details do not state thickness, so buyers who need that specification should consider that boundary.

#4 · Grease-Free Choice

4. Denco 32-Inch Slick Disc

• Weight: 5 lb

Best for: Grease-free 32-inch articulation.

Why it ranks #4: Its 32-inch, 1/4-inch-thick slick disc is designed as a low-friction alternative to fifth-wheel grease, though no retainer is listed.

Denco’s 32-inch SLIK DISC uses a smooth, low-friction surface to help trailers pivot during turns and maneuvers without traditional fifth-wheel grease. Its 1/4-inch thickness and heavy-duty description give buyers concrete sizing and construction details for a cleaner coupling routine.

The 32-inch diameter provides the stated contact size for the tractor fifth wheel and trailer, while the 1/4-inch thickness helps buyers assess the plate against their setup. Denco says the smooth, low-friction surface supports freer trailer articulation during turns and maneuvers. Replacing traditional grease with the disc can reduce mess and maintenance time, according to the supplied description. The available details focus on the plate itself; they do not list a retention clip or an included installation accessory.

Skip it if you need a small RV kingpin disc; CURT 16722 is a listed 12-inch option with self-cleaning grooves.

This suits operators seeking a 32-inch grease alternative that supports trailer articulation and a cleaner service routine. Its stated dimensions are the key boundary: buyers should select it only when a 32-inch disc matches their setup.

#5

5. CURT 12-Inch Plate

• Weight: 9.44 oz
• Material: Plastic
• Compatible with Vehicle Type: Trailer

Best for: Grooved 12-inch RV plates.

Why it ranks #5: The 12-inch plastic plate has wear-resistant and self-cleaning-groove features, but its compact size is less aligned with semi-focused 32- and 36-inch discs.

Self-cleaning grooves distinguish the CURT 16722’s 12-inch plastic plate, adding a specific surface feature to its grease-free approach. The plate creates a lubricating buffer between the hitch head and kingpin box, helping protect the hitch head from wear while avoiding grease cleanup after towing.

The 12-inch diameter gives RV and trailer owners a defined plate size to compare with their hitch setup. CURT describes the plastic disc as a lubricating buffer between the hitch head plate and kingpin box, helping protect the hitch head from wear under heavy-duty towing. Its self-cleaning grooves provide a named surface feature, while the grease-free format avoids the cleanup associated with grease. The included component is the lube plate, so buyers should account for that when planning installation.

Skip it if you need a 32-inch truck disc with a steel clip; Buyers Products FWD32 lists both.

Choose this CURT plate for a 12-inch hitch application where self-cleaning grooves and a grease-free buffer are useful. Its compact diameter is the main boundary, so it is not the large-disc choice for truck setups.

#6

6. TonGass 12-Inch Plate

• Material: Plastic
• Compatible with Vehicle Type: Trailer

Best for: 12-inch TonGass plate shoppers.

Why it ranks #6: This 12-inch PP plastic plate is a smaller trailer-oriented option; its stated material and diameter make it a different fit category from truck discs.

The 12-inch TonGass plate offers a larger RV-oriented format than the brand’s listed 10-inch option, while retaining its stated PP plastic construction. Its grease-free surface is intended to limit residue and protect the fifth wheel from friction and wear during towing.

A 12-inch diameter gives this plate a clear size distinction for buyers whose trailer setup calls for that format. TonGass describes the plastic as high-density PP with good wear resistance, linking the material to protection against friction and wear. Using the plate instead of greasing the fifth-wheel head avoids the greasy residue identified in the listing. Trailer compatibility is specified, but the supplied details do not state a pin diameter, so the listed diameter is the primary sizing information.

Skip it if you require a listed standard 2-7/8-inch pin fit; TonGass LubePlateB2pk-10in names that compatibility.

Trailer owners needing a 12-inch plastic plate and wanting to avoid grease residue are the intended audience. The material and diameter are stated, but the supplied specifications leave pin diameter unstated for fit evaluation.

#7

7. scottchen PRO 10-Inch White Plate

• Weight: 0.18 kg
• Material: polyethylene
• Compatible with Vehicle Type: Trailer

Best for: Standard-pin RV installations.

Why it ranks #7: The 10-inch polyethylene plate specifies a standard 2-7/8-inch pin fit, but its compact RV/trailer format is not a semi-size disc.

A stated fit for a standard 2-7/8-inch pin gives this 10-inch scottchen PRO plate a clear compatibility target for RV and trailer owners. Its heavy-duty polyethylene disc presses onto the kingpin, offering a grease-free approach to protecting the fifth wheel from towing friction and wear.

The listed 2-7/8-inch pin fit helps buyers assess compatibility before installation, while the 10-inch diameter identifies the plate format. Its polyethylene construction is described as high-density and wear-resistant, supporting the stated role of protecting the fifth wheel against friction and wear during towing. The press-on installation in the title offers a direct fitting workflow, and using a plate avoids the messy grease residue the listing aims to replace. The specifications identify trailer compatibility.

Skip it if you want two 10-inch plates in one listing; Threlaco JYD1808 lists a two-piece set.

RV and trailer owners with a standard 2-7/8-inch pin seeking a press-on polyethylene plate are the natural buyers. Its stated pin size is the key boundary; this is not presented as a universal-fit disc.

#8

8. TonGass 10-Inch Plate

• Weight: 0.39 kg
• Material: Plastic
• Compatible with Vehicle Type: Trailer

Best for: Standard-pin plastic RV plates.

Why it ranks #8: This PP plastic plate is listed for trailers and fits a smaller 10-inch category, placing it behind the full-size truck-focused discs.

A listed fit for a standard 2-7/8-inch pin gives this TonGass 10-inch plate a specific RV compatibility target. Its PP plastic construction is described as high-density and wear-resistant, while the plate replaces grease with a cleaner surface intended to limit friction and wear during towing.

The 10-inch size and stated standard 2-7/8-inch pin fit help buyers assess whether this plate matches their hitch before installation. TonGass identifies PP plastic as the material and describes it as high-density with good wear resistance, connecting construction to its stated friction-protection role. The listing positions the plate as an alternative to greasing the fifth-wheel head, so buyers can avoid dealing with greasy residue. The supplied compatibility is for trailers.

Skip it if you need a 12-inch plate with self-cleaning grooves; CURT 16722 lists that larger size and surface feature.

Trailer owners with a standard 2-7/8-inch pin seeking a 10-inch plastic plate may appreciate the stated wear resistance and grease-free use. The pin measurement is the central fit boundary to check against the setup.

#9

9. Threlaco 10-Inch Plate

• Weight: 13.76 oz
• Compatible with Vehicle Type: RV

Best for: RV owners wanting a spare.

Why it ranks #9: The listing includes two 10-inch RV plates for replacement coverage, but gives no truck-specific diameter or pin compatibility for semi use.

Two 10-inch plates give the Threlaco listing an immediate spare advantage for RV owners who want another disc available after installation. The plates are described as protecting the hitch plate from friction and wear, while the compact size separates them from the larger commercial-truck discs.

Each 10-inch plate is intended to provide a protective surface for an RV fifth-wheel hitch, with the stated aim of reducing friction and wear. The two-piece quantity lets an owner keep an extra plate on hand rather than relying on a single replacement. The listing identifies RV compatibility and includes two plates, but does not provide a pin diameter or material in the supplied specifications. Buyers therefore get a clear size and quantity, with less detail for checking precise compatibility.

Skip it if you need a stated standard 2-7/8-inch pin fit; scottchen PRO TCD-01 lists that compatibility.

RV owners seeking two 10-inch plates, including one to keep as a spare, are the best match. The listing supplies size and vehicle category but not pin diameter or material, which limits fit and construction detail.

#10

10. scottchen PRO 10-Inch Black Plate

• Weight: 0.44 kg
• Material: Polyethylene
• Compatible with Vehicle Type: RV

Best for: Compact RV hitch plate buyers.

Why it ranks #10: This two-pack is a polyethylene RV-compatible plate without a stated semi fit or pin measurement, making it the least supported choice for this use.

A 10-inch polyethylene plate gives the scottchen PRO TCD-03 a compact format for RV fifth-wheel applications, and its stated low-friction PTFE-style design aims to reduce noise and provide cushioning. The listing identifies a two-pack, giving buyers an extra plate for a replacement or spare.

The 10-inch format distinguishes this plate from the larger truck-oriented discs in the roundup, making it a compact choice for RV owners whose hitch takes that size. Its high-density, wear-resistant polyethylene is described as protecting the fifth wheel from friction and wear during towing. The PTFE-style low-friction design is also presented as a way to reduce noise and add cushioning. The supplied specifications identify RV compatibility, but do not state a pin diameter, so the plate size remains the main fit detail provided.

Skip it if you need a listed standard 2-7/8-inch pin fit; TonGass LubePlateB2pk-10in names that pin size.

RV owners seeking a compact polyethylene plate with stated friction protection, noise reduction, and cushioning may find this a match. Its 10-inch size is central, and the supplied specifications leave pin diameter unstated.
