Best Gooseneck Adapter For Bumper Pull Trailer

#1 · Best Overall

1. Lamerto C5G1216

• Material: Stainless Steel
• Compatible with Vehicle Type: Car, Trailer, Truck
• Weight: 27.8 kg

Best for: Adjustable cushioned RV towing.

Why it ranks #1: Its 12-to-16-inch adjustment, listed 20,000-pound gross capacity, cushioning, and included safety chain make it a well-specified fifth-wheel conversion option.

A 12-to-16-inch adjustable height range lets the Lamerto C5G1216 adapt a fifth-wheel kingpin to a gooseneck ball while helping match the trailer and truck setup. Its built-in cushioning is intended to reduce shock and vibration, making it a candidate for RV owners who want height adjustment and a softer towing connection.

The sliding collar and set screws let you lock a selected height between 12 and 16 inches, which helps accommodate different truck and trailer combinations. A cushioning structure reduces shock and vibration during travel, with the stated aim of protecting both the trailer kingpin and gooseneck hitch. The adapter mounts directly to the kingpin and converts the connection without drilling or welding; the supplied safety chain adds a towing-safety component to the setup.

Skip it if you need a setup rated above 20,000 pounds; the NUOVEPE Gooseneck Hitch Plate lists a 30,000-pound gross trailer rating.

Choose this Lamerto adapter for an RV or camper owner converting a kingpin to a gooseneck connection, especially when height adjustment and cushioning matter. Its stated 20,000-pound gross capacity is an important boundary for trailer selection.

#2 · Cushioned Ride

2. Convert-A-Ball C5G1216

• Weight: 67 lb

Best for: Cast-steel shock cushioning.

Why it ranks #2: It lists 20,000-pound towing and 4,000-pound pin-weight capacities, adjustable 12-to-16-inch height, and poly cushions intended to reduce shock and vibration.

Poly cushions inside the Convert-A-Ball C5G1216 absorb shock, with the stated aim of reducing bounce and vibration between a fifth-wheel trailer and vehicle. Its 12-to-16-inch adjustable heights accommodate multiple applications, while the 20,000-pound towing and 4,000-pound pin-weight capacities define the load range to consider.

The poly cushions absorb shock to reduce bounce and vibration, which can make the connection less jarring for both trailer and vehicle. Adjustable height from 12 to 16 inches supports multiple towing applications by allowing a height choice within that range. Durable cast-steel construction forms the adapter body, and the listed 20,000-pound towing capacity and 4,000-pound pin-weight capacity provide concrete limits for checking a trailer setup.

Skip it if you need safety chains specified in the listing; Lamerto’s C5G1216 includes a heavy-duty safety chain with its cushioned adapter.

Choose Convert-A-Ball for a fifth-wheel-to-gooseneck conversion when shock absorption, adjustable height, and the stated load capacities align with your trailer. The supplied details do not mention safety chains, so that is a relevant equipment boundary.

#3 · Dual-Axis Cushioning

3. B&W RVGN3153

• Compatible with Vehicle Type: RV

Best for: Cushioned long-haul RV towing.

Why it ranks #3: Its SumoSpring system and dual-axis cushioning address vertical and horizontal movement; the listed 3,250-pound pin rating is a key limit to verify.

B&W’s integrated SumoSpring suspension and dual-axis cushioning target both vertical and horizontal trailer movement, helping reduce chucking and porpoising on the road. That motion control makes this adapter relevant to RV owners traveling rough backroads or undertaking long hauls, where controlling movement between truck and trailer is a central consideration.

The SumoSpring system absorbs movement, while dual-axis cushioning manages vertical and horizontal motion; together, these features are intended to soften the push and pull between truck and RV. The supplied description also identifies reduced chucking and porpoising, useful benefits for rough-road travel and long-distance towing. Mounting hardware and an installation guide are included, giving buyers components and guidance for setup, while the product title specifies a 3,250-pound pin figure.

Skip it if you need a listed 20,000-pound gross trailer rating; the Lamerto C5G1216 specifies that capacity and adjustable height.

B&W’s adapter fits RV owners who prioritize managing road movement through SumoSpring suspension and dual-axis cushioning. Consider the listed 3,250-pound pin figure when evaluating your trailer’s load; the supplied details emphasize ride control rather than a gross trailer rating.

4. GELUOXI C5G1216

• Material: Alloy Steel
• Compatible with Vehicle Type: Trailer, Truck
• Weight: 27.8 kg

Best for: Height-adjustable cushioned setup.

Why it ranks #4: This cushioned kingpin adapter lists 12-to-16-inch adjustment, 20,000-pound gross capacity, 4,000-pound tongue weight, and included safety chains.

GELUOXI’s C5G1216 combines 12-to-16-inch height adjustment with 360-degree cushioning and vertical movement control, enabling a more tailored fifth-wheel-to-gooseneck connection. Its stated 20,000-pound gross capacity and included safety chains make it relevant to RV and trailer owners who want both adjustable positioning and a cushioned hitch interface.

A sliding collar with set screws allows adjustment from 12 to 16 inches, helping match the adapter’s height to a truck and trailer combination. The product description says cushioning works 360 degrees as well as up and down, intended to manage movement in multiple directions. It lists 20,000 pounds gross vehicle weight and 4,000 pounds tongue weight, giving buyers load figures to assess alongside the included safety chains.

Skip it if you require an explicitly stated no-drilling installation; Lamerto’s C5G1216 says it mounts without drilling or welding.

This GELUOXI adapter is suited to trailer owners needing height adjustment, cushioning, and the listed 20,000-pound gross capacity. Its 4,000-pound tongue-weight figure is also relevant, but the supplied details do not explain the installation method.

#5

5. MFZDQL C5G1216

• Material: Alloy Steel
• Compatible with Vehicle Type: Trailer
• Weight: 23.13 kg

Best for: Adjustable cushioned caravan towing.

Why it ranks #5: The listing specifies adjustable 12-to-16-inch height, 20,000-pound towing capacity, 4,000-pound maximum vertical pin weight, and a two-year warranty.

MFZDQL’s C5G1216 combines 12-to-16-inch height adjustment with cushioning, enabling height matching and a more buffered connection when converting a trailer kingpin to a gooseneck hitch. Its stated 20,000-pound towing capacity and 4,000-pound maximum vertical pin weight give buyers useful load limits for camper, caravan, and trailer applications.

The adjustable 12-to-16-inch range helps accommodate different kingpin-box and truck combinations, while the cushioned design is intended to reduce movement at the connection. The listing states a 20,000-pound towing capacity and maximum vertical pin weight of 4,000 pounds, so buyers can compare both figures against their trailer requirements. Alloy-steel construction is specified, and the adapter’s stated role is converting a trailer’s kingpin for a gooseneck hitch.

Skip it if you require listed safety chains; GELUOXI’s C5G1216 specifically includes safety chains with its adjustable cushioned adapter.

MFZDQL’s adapter fits camper, caravan, and trailer owners seeking adjustable height, cushioning, and stated 20,000-pound capacity. Check the 4,000-pound vertical pin limit against your setup, and note that safety chains are not mentioned in the supplied listing.

#6

6. Misakomo Kingpin Adapter

• Material: Alloy Steel
• Compatible with Vehicle Type: Truck, Tractor, Trailer

Best for: Forged-steel kingpin adapter.

Why it ranks #6: Its one-piece forged-steel construction connects a 2-inch kingpin to a 2-5/16-inch gooseneck ball, but the supplied data gives no capacity figure.

One-piece forged-steel construction is the defining feature of Misakomo’s kingpin-to-gooseneck adapter, offering a solid connection for converting a fifth-wheel trailer to a gooseneck ball. Its protective coating is specified for rust resistance, a practical detail for owners who tow in changing weather and want a straightforward adapter rather than a height-adjustable model.

The forged-steel body and one-piece machining are described as distributing force uniformly and resisting breakage, supporting the adapter’s role between a kingpin and gooseneck ball. A protective coating is intended to resist rust through exposure to severe weather. The listed ball size is 2-5/16 inches and the kingpin size is 2 inches, giving buyers concrete connection dimensions to check against their towing components before choosing this fixed-style adapter.

Skip it if you need height adjustment or cushioning; Lamerto’s C5G1216 offers a 12-to-16-inch range and a cushioned structure.

This Misakomo adapter suits buyers prioritizing a forged, one-piece steel kingpin connection and the listed 2-5/16-inch ball size. Its supplied details do not state a height-adjustment range, so it is less suited to setups requiring that adjustment.

#7 · Rail-Mount Option

7. CURT 16085 Spyder

• Material: carbide
• Compatible with Vehicle Type: Truck
• Weight: 50 lb

Best for: Rail-equipped pickup versatility.

Why it ranks #7: This rail-mounted adapter fits industry-standard fifth-wheel base rails, uses a welded 2-5/16-inch ball, and lists a 25,000-pound gross trailer rating.

CURT’s four-pin installation and removal lets a pickup with industry-standard fifth-wheel rails switch to a gooseneck connection while restoring truck-bed access when the adapter is removed. The Spyder is rated for up to 25,000 pounds gross trailer weight and uses a welded 2-5/16-inch ball, making it a rail-focused option for versatile towing.

The adapter mounts to all industry-standard fifth-wheel base rails, so owners with that rail setup can use a gooseneck trailer without replacing the rail system. Its four-pin installation and removal simplify taking the unit out when truck-bed access is needed. A welded 2-5/16-inch trailer ball provides the gooseneck connection, and the 25,000-pound gross trailer rating gives buyers a stated capacity to compare with their trailer requirements.

Skip it if you do not have fifth-wheel base rails; the Eaz-Lift 48490 is listed as a 17-inch gooseneck adapter without rail-mount details.

Pick the CURT Spyder if your pickup already has industry-standard fifth-wheel rails and you want removable gooseneck functionality with truck-bed access afterward. Its rail-dependent mounting and 25,000-pound rating define the key fit boundaries.

#8 · Highest Capacity

8. NUOVEPE Hitch Plate

• Material: Heavy Duty Hardened Steel
• Compatible with Vehicle Type: Gooseneck Trailers, Truck
• Weight: 15.94 kg

Best for: High-capacity rail-mounted towing.

Why it ranks #8: Its 30,000-pound gross trailer rating and 6,500-pound vertical-load limit are the highest stated here, but it converts standard fifth-wheel rails.

A 30,000-pound gross trailer rating and 6,500-pound maximum vertical load make the NUOVEPE plate the highest-capacity choice among these listed rail adapters. It fits standard fifth-wheel rails and adds a 2-5/16-inch ball, enabling a rail-equipped truck to connect with gooseneck trailers, including the larger trailer types named in its listing.

The plate fits industrial-standard fifth-wheel rails, allowing owners to use an existing rail setup for a gooseneck connection. Its 2-5/16-inch ball provides the stated coupling point, while the 30,000-pound gross trailer rating and 6,500-pound vertical-load limit specify the product’s capacity boundaries. Heavy-duty hardened steel construction supports the plate’s intended demanding towing use, and the listing names dump, boat, farm, and other large trailers as applications.

Skip it if you do not have standard fifth-wheel rails; the Eaz-Lift 48490 listing does not specify a rail-mounted plate.

This NUOVEPE plate suits rail-equipped truck owners hauling gooseneck trailers who need its stated high gross and vertical-load ratings. Its standard-rail mounting requirement is the key fit consideration before selecting it.

#9

9. Eaz-Lift 48490

• Material: Blend
• Compatible with Vehicle Type: Trailer, Truck
• Weight: 55.3 lb

Best for: Fixed 17-inch conversion height.

Why it ranks #9: This 17-inch adapter converts fifth-wheel trailers to gooseneck towing, but the supplied specifications do not state a capacity or adjustable range.

Eaz-Lift’s specified 17-inch height gives buyers a concrete dimension for converting a fifth-wheel trailer to a gooseneck connection. The listing describes the adapter as easy to install and includes the 17-inch gooseneck adapter, making it a simple option to evaluate when that fixed height suits the truck-and-trailer setup.

The 17-inch height is the central fit detail, allowing buyers to compare the adapter’s stated dimension with their towing geometry before installation. Its stated purpose is converting fifth-wheel trailers to gooseneck trailers, while the listing describes installation as easy. The product information does not provide a towing-capacity figure or adjustment range, so this model is best assessed on its fixed dimension and conversion role rather than an assumed load rating.

Skip it if you need a published capacity figure; the CURT 16085 Spyder lists a 25,000-pound gross trailer rating.

Consider the Eaz-Lift 48490 if its 17-inch height matches your setup and you want a stated fifth-wheel-to-gooseneck conversion. The supplied specifications do not give a towing-capacity rating or adjustment range.

#10

10. TOWGUARD TOW-051

• Material: Alloy Steel
• Compatible with Vehicle Type: Fifth Wheel Trailer, Gooseneck Trailer, Heavy…
• Weight: 22.5 kg

Best for: Remote-release coupler access.

Why it ranks #10: Its adjustable coupler and remote release are described for gooseneck towing, but the listed maximum capacity is only 5,000 pounds and fit details are unclear.

A remote release system lets the TOWGUARD coupler be released without climbing into the truck bed, making uncoupling access its most distinctive practical feature. Adjustable height is also specified to help level different truck and trailer combinations, so this is a fit for buyers prioritizing release convenience and setup positioning.

The remote release is intended to let users uncouple without climbing into the truck bed, which can simplify access during the disconnect workflow. Adjustable height helps match truck and trailer combinations and supports a more level trailer stance. The listing gives a maximum towing capacity of 5,000 pounds, an important load limit to weigh against a trailer’s requirements. Its round-tube coupler is described as an adjustable-height gooseneck design.

Skip it if you tow loads above 5,000 pounds; the CURT 16085 Spyder lists a 25,000-pound gross trailer rating.

The TOWGUARD coupler suits buyers who value remote uncoupling and adjustable leveling for a compatible lighter towing setup. Its listed 5,000-pound maximum capacity is the critical boundary, so match it carefully to the trailer load.
