Best 5Th Wheel Gooseneck Hitch for Rails and Kingpin Boxes

#1 · Best Overall

1. CURT 16085 Spyder

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

Best for: Standard-rail gooseneck towing.

Why it ranks #1: Fits industry-standard 5th wheel rails, includes a 2-5/16-inch ball, and is rated for 25,000 pounds with four-pin removal.

The CURT 16085 Spyder converts industry-standard fifth-wheel rails to a gooseneck connection, giving rail-equipped pickup owners a way to tow a gooseneck trailer with their existing rail setup. Its welded 2-5/16-inch ball and 25,000-pound gross trailer weight rating identify the connection and capacity at a glance.

The Spyder mounts to all industry-standard fifth-wheel base rails, so its conversion function is aimed at pickups that already have that rail arrangement. Four-pin installation and removal supports taking the hitch out when access to the truck bed is needed. The welded 2-5/16-inch ball supplies the specified trailer connection, and the listed gross trailer weight rating is up to 25,000 pounds. Together, the rail mount and removable design make it a practical option for owners who alternate between towing and bed use.

Skip it if you want a listed rearward ball offset; the CURT 16055 offers a reversible 3-inch rearward offset.

This fits pickup owners with industry-standard fifth-wheel rails who want a removable gooseneck connection and a stated 25,000-pound gross trailer weight rating. Its mounting depends on having those rails, and the listing does not specify an offset option.

#2 · Highest Listed Capacity

2. NUOVEPE Gooseneck 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 #2: A rail-mounted plate for standard 5th wheel rails, with a stated 30,000-pound gross trailer weight rating and 6,500-pound vertical load.

A 30,000-pound gross trailer weight rating sets this NUOVEPE plate apart for buyers with demanding gooseneck towing requirements. It fits industry-standard fifth-wheel rails and includes a 2-5/16-inch ball, letting a rail-equipped truck use those rails for a gooseneck connection rather than a kingpin-mounted adapter.

The plate’s stated compatibility with all industry-standard fifth-wheel rails means buyers with that rail setup can use it as a gooseneck conversion. Its 2-5/16-inch ball supplies the listed trailer connection, while the 30,000-pound gross trailer weight rating and 6,500-pound maximum vertical load provide two separate limits to consider. Heavy-duty hardened steel is the specified material. The product is described for use with gooseneck, dump, boat, and farm-related trailers, though the truck’s rail arrangement remains central to fit.

Skip it if you need an adapter that mounts to a trailer kingpin box; the Lamerto C5G1216 is listed for that type of connection.

This plate suits truck owners with standard fifth-wheel rails who need a high-capacity gooseneck connection for compatible trailers. Its 30,000-pound gross trailer weight and 6,500-pound vertical load limits, along with rail fit, are essential boundaries.

#3 · Best Offset Option

3. CURT 16055 Rail Gooseneck Hitch

• Material: Alloy Steel
• Compatible with Vehicle Type: Truck
• Weight: 40 lb

Best for: Rail-equipped truck owners.

Why it ranks #3: Fits industry-standard 5th wheel rails, has a 25,000-pound rating, and can be flipped for a 3-inch rearward offset.

Four-pin installation and removal lets this CURT adapter switch a rail-equipped pickup between gooseneck towing and open-bed use. Its welded 2-5/16-inch ball provides the trailer connection, while the reversible 3-inch offset gives buyers a way to position the ball behind the axle when that placement suits their setup.

The adapter mounts to industry-standard fifth-wheel base rails, so a truck with those rails can connect a gooseneck trailer without replacing its rail system. Its four-pin installation and removal makes returning the bed to other uses more straightforward. The welded 2-5/16-inch ball is the connection point, and the option to place it over the axle or flip it for a 3-inch rearward offset gives buyers two positioning choices. CURT lists a 25,000-pound rating.

Skip it if you need an adapter that mounts directly to a trailer kingpin; the Lamerto C5G1216 is listed for kingpin-box mounting.

This suits pickup owners who already have standard fifth-wheel rails and want a removable gooseneck connection, especially when ball positioning matters. It is not a direct kingpin-mounted adapter, so the truck’s rail setup is central to the choice.

#4 · Lightweight Kingpin Adapter

4. Andersen Gen 3 Ultimate

• Material: Aluminum
• Compatible with Vehicle Type: Truck
• Weight: 52 lb

Best for: One-person removable hitch users.

Why it ranks #4: Converts a fifth-wheel connection with a 24,000-pound rating, 4,500-pound tongue limit, two height settings, and a 37-pound advertised product weight.

At 37 pounds, the Andersen Gen 3 Ultimate Connection is specified for one-person installation or removal in under five minutes, making handling a central advantage for buyers who switch towing setups. It supports up to 24,000 pounds GTWR and offers two height settings, with remote latching for operation from a distance.

The two settings place the top of the ball mount 17-9/16 or 19-9/16 inches above the truck bed, giving buyers a choice when matching truck and trailer heights. A compact 3-1/4-inch offset base provides the stated offset while taking up less space. The 37-pound weight supports the listed one-person install or removal in under five minutes, and the remote latching cable lets the user operate the latch remotely. Ratings are 24,000 pounds GTWR and 4,500 pounds tongue weight.

Skip it if you need a continuous 12-to-16-inch height adjustment; the Lamerto C5G1216 offers that adjustable range.

This Andersen suits truck owners who value a lighter, quick-to-handle connection with remote latching and can use one of its two height settings. Check the stated ball-mount heights, offset, and weight ratings against the trailer and truck arrangement.

#5 · Best Adjustable Cushioned Adapter

5. Lamerto C5G1216

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

Best for: Height-adjustable RV adapter.

Why it ranks #5: A kingpin-mounted cushioned adapter adjusts from 12 to 16 inches and lists a 20,000-pound rating and included safety chain.

A sliding collar adjusts this Lamerto adapter from 12 to 16 inches, letting buyers set the height for a fifth-wheel kingpin-box conversion to gooseneck towing. Its built-in cushioning addresses shock and vibration on the road, while the included safety chain adds a specified safety component to the setup.

The adjustable 12-to-16-inch height and sliding collar with set screws let the body be positioned and locked to suit the towing arrangement. That flexibility can help buyers accommodate different trailer and truck-bed heights without a fixed-height adapter. Lamerto also specifies a built-in cushioning structure to reduce shock and vibration, with the stated aim of supporting stability and protecting the kingpin and gooseneck hitch. The listed kit includes a heavy-duty safety chain and is rated for 20,000 pounds.

Skip it if you need a rail-mounted plate rather than a kingpin-box adapter; the NUOVEPE rail plate fits standard fifth-wheel rails.

This is a fit for RV or trailer owners converting a kingpin-box connection who need adjustable height, cushioning, and an included safety chain. Its listed capacity is 20,000 pounds, so that rating is a key boundary for the towing setup.

#6

6. GELUOXI C5G1216

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

Best for: Cushioned height-adjustment buyers.

Why it ranks #6: This cushioned kingpin adapter adjusts from 12 to 16 inches and lists a 20,000-pound capacity, 4,000-pound tongue weight, and safety chains.

Full 360-degree cushioning, plus up-and-down movement, distinguishes this GELUOXI adapter for buyers seeking a cushioned fifth-wheel-to-gooseneck conversion. Its height adjusts from 12 to 16 inches, and the stated 20,000-pound gross vehicle weight capacity and 4,000-pound tongue weight rating give shoppers concrete limits to check against their trailer.

The sliding collar and set screws provide adjustment from 12 to 16 inches, allowing the adapter’s height to be set and secured for the towing arrangement. GELUOXI specifies cushioning in 360 degrees as well as up-and-down movement, features intended to address motion during towing. The adapter connects a trailer kingpin to a gooseneck hitch and includes safety chains. Its listed ratings are 20,000 pounds gross vehicle weight and 4,000 pounds tongue weight, useful limits when assessing a match.

Skip it if you need a rail-mounted plate; the NUOVEPE gooseneck hitch plate fits standard fifth-wheel rails instead of converting a kingpin.

Consider this for a trailer owner who wants an adjustable, cushioned kingpin-to-gooseneck connection and can work within its stated weight ratings. The listed 20,000-pound gross vehicle weight and 4,000-pound tongue weight are important fit boundaries.

#7

7. Bicos C5G1216

• Compatible with Vehicle Type: Truck

Best for: Adjustable cushioned adapter seekers.

Why it ranks #7: A cushioned 12-to-16-inch adapter for 2-5/16-inch gooseneck balls; the listing identifies C5G1216 but provides fewer capacity details.

The Bicos C5G1216 is listed as a cushioned adapter with an adjustable 12-to-16-inch height, combining movement accommodation with a range buyers can use when setting up a fifth-wheel-to-gooseneck conversion. Its stated application is a 2-5/16-inch gooseneck ball, and the product title also identifies a safety chain.

The 12-to-16-inch adjustable height gives the adapter a range rather than a single fixed position, which buyers can consider when matching a trailer and truck setup. Bicos identifies cushioning in the product title, while the listed 2-5/16-inch gooseneck ball application states the connection requirement. The title also mentions a safety chain. The supplied information does not state a towing-capacity or tongue-weight figure, so those limits cannot be compared from the available product facts.

Skip it if you need a stated towing capacity; the GELUOXI C5G1216 lists a 20,000-pound gross vehicle weight capacity.

This can suit buyers seeking an adjustable, cushioned C5G1216-style conversion for a 2-5/16-inch gooseneck ball. The supplied listing does not state a capacity figure, so that information is an important boundary when assessing trailer suitability.

#8

8. NBJINGYI Gooseneck Adapter

• Material: Metal
• Compatible with Vehicle Type: trailer

Best for: Remote-release trailer owners.

Why it ranks #8: A 15-inch kingpin-to-gooseneck adapter rated at 20,000 pounds, with a self-latching coupler and remote release cable.

A self-latching coupler with a remote release cable lets this NBJINGYI adapter handle coupling and release without relying on a listed manual latch at the connection point. Its 15-inch length and 20,000-pound capacity are specified alongside compatibility with gooseneck hitches using a 2-5/16-inch ball.

Compatibility with any gooseneck hitch using a 2-5/16-inch ball gives this adapter a clear connection requirement for buyers to check. The 15-inch length and 20,000-pound capacity provide further concrete parameters for assessing the trailer setup. A self-latching coupler is paired with a remote release cable, which supports latching and release from the cable rather than requiring the release point to be at the coupler. NBJINGYI lists RVs and horse trailers among its intended applications.

Skip it if you need an adjustable 12-to-16-inch cushioned adapter; the GELUOXI C5G1216 lists that range and cushioning.

This suits RV or horse-trailer owners seeking a 15-inch adapter with a self-latching coupler and remote release cable. Its 2-5/16-inch ball compatibility and 20,000-pound capacity define key setup limits to check before choosing it.

#9

9. PSAUTO Cushioned Adapter

• Material: Alloy Steel
• Compatible with Vehicle Type: Fifth Wheel RV

Best for: Cushioned conversion shoppers.

Why it ranks #9: A 12-to-16-inch adjustable cushioned adapter for fifth-wheel conversion, but the supplied listing does not give a towing rating.

A cushioned conversion from fifth-wheel to gooseneck is the PSAUTO adapter’s defining feature, with the supplied description stating that the change can be made within minutes. Its title lists an adjustable height range of 12 to 16 inches, giving buyers a stated span to consider when choosing a converter.

The title identifies a 12-to-16-inch adjustable height range, which gives buyers more than one fixed height to work with when positioning a fifth-wheel-to-gooseneck converter. The product description says the adapter is cushioned and converts a fifth wheel to a gooseneck within minutes, making it relevant to owners looking to change coupling type. PSAUTO lists a maximum towing capacity of 9,071.85 kilograms. The supplied details do not specify a safety chain or adjustment mechanism.

Skip it if you need a stated safety chain in the kit; the Lamerto C5G1216 lists a heavy-duty safety chain.

This may suit a fifth-wheel RV owner seeking a cushioned gooseneck conversion with the title’s 12-to-16-inch adjustment range. Its listed capacity is 9,071.85 kilograms; check that rating and the available product details against your towing needs.

#10

10. Misakomo Kingpin Adapter

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

Best for: Forged-steel kingpin adapter buyers.

Why it ranks #10: This forged-steel kingpin-to-ball adapter lists a 2-5/16-inch ball connection but supplies no towing capacity or height range.

One-piece machined forged steel is the defining construction of this Misakomo kingpin-to-gooseneck ball adapter, with the product description citing even force distribution and resistance to breakage. Its listed connection sizes are a 2-inch kingpin and a 2-5/16-inch ball, helping buyers identify the intended coupling arrangement.

The one-piece machining and forged-steel construction give the adapter a single solid body, while its protective coating is specified for rust resistance. Those features matter to buyers choosing a kingpin-to-ball connection for outdoor towing. The listed 2-inch kingpin size and 2-5/16-inch ball size make the intended interface explicit. Misakomo also identifies truck, tractor, and trailer compatibility, but the supplied details do not state a towing-capacity figure, so capacity cannot be assessed from the listed information.

Skip it if you require a stated capacity before selection; the CURT 16085 Spyder lists a 25,000-pound gross trailer weight rating.

This is for buyers seeking a forged-steel kingpin-to-gooseneck ball adapter with the listed 2-inch and 2-5/16-inch interfaces. Because the supplied information gives no capacity figure, that missing rating is a boundary for evaluating a towing match.
