Best Gooseneck To Fifth Wheel Adapter Plate for Your Setup

#1 · Best Overall

1. springcraze Gooseneck Ball Adapter

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

Best for: Raised adapter with rust protection.

Why it ranks #1: Its 2-5/16-inch ball and 2-inch kingpin directly address the gooseneck-to-fifth-wheel connection, with a stated 30,000-pound GVW rating.

A 1.5-inch raised base adds ground clearance, making the springcraze adapter distinct for towing situations where that lift is useful. It combines a 2-inch kingpin and 2-5/16-inch gooseneck ball with a 30,000-pound GVW rating, plus powder-coat and phosphate protection against weather exposure.

The 1.5-inch lift is intended to increase ground clearance, while the forged alloy-steel construction and reinforcing-rib structure are specified for a heavy-duty adapter. Its 2-inch kingpin and 2-5/16-inch ball define the connection sizes, and the 30,000-pound GVW rating gives a stated capacity to check. Powder coating and phosphate treatment are listed as protection against salt spray, rain, and temperature shock; a PU anti-tilt washer and fifth-wheel lube plate are also included.

Skip it if you need a stated four-pin rail installation; the CURT 16085 lists four-pin mounting and removal for standard fifth-wheel rails.

This springcraze adapter suits buyers needing a raised connection and the listed kingpin and ball sizes for tractor or trailer use. Check that the 1.5-inch lift and 30,000-pound GVW rating suit the specific towing arrangement.

#2 · Best Tube Fit

2. FlexHitch GC-091S Adapter

• Material: Alloy Steel
• Compatible with Vehicle Type: Truck

Best for: Four-inch square-tube trailer fit.

Why it ranks #2: The title specifically identifies a gooseneck-to-fifth-wheel adapter for a 4-inch square outer tube; the listing also includes two lube plates.

Compatibility with a 4-inch square outer tube is the defining detail of this FlexHitch adapter, making that trailer dimension the key fit consideration. Its alloy-steel construction and included pair of fifth-wheel lube plates provide a specifically described component package for converting a gooseneck tube setup to a fifth-wheel connection.

The 4-inch square outer-tube fit gives owners a concrete trailer-side dimension to check before choosing the adapter, rather than relying on a general compatibility claim. Alloy steel is the listed material, while the two included fifth-wheel lube plates provide accessories for the fifth-wheel interface. The product is identified for truck compatibility, but the supplied information does not give a towing-capacity rating, installation steps, or additional fit dimensions; buyers should base selection on the stated tube size and confirm their required capacity elsewhere.

Skip it if you require a stated towing-capacity rating; the HENTYMAX QQTT123 lists 30,000 pounds GTW and 7,500 pounds tongue weight.

This is a fit-focused option for truck owners whose trailer has the specified 4-inch square outer tube and who want the included lube plates. Its supplied details omit capacity figures, so it is not suited to buyers who need one stated rating.

#3 · Highest Capacity

3. NUOVEPE Hitch Plate

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

Best for: High-capacity standard-rail towing.

Why it ranks #3: Although it converts standard fifth-wheel rails to gooseneck, its 30,000-pound GTW and 6,500-pound vertical-load ratings are clearly stated.

A 30,000-pound gross trailer weight rating paired with a 6,500-pound maximum vertical load gives the NUOVEPE plate a clearly stated capacity profile for demanding towing. Its 2-5/16-inch ball converts standard fifth-wheel rails to a gooseneck connection, letting truck owners use that rail setup for gooseneck trailers.

The heavy-duty hardened-steel construction and stated 30,000-pound GTW rating address strength and towing capacity for large trailers, boat trailers, or farm equipment. A 6,500-pound maximum vertical load supplies a separate limit to consider when evaluating the trailer and truck combination. Because the plate fits standard fifth-wheel rails and uses a 2-5/16-inch ball, it offers a direct route to gooseneck towing without replacing the rail system; the listed facts do not specify installation hardware or removal steps.

Skip it if you need a stated tongue-load limit above 6,500 pounds; this plate's listed vertical-load ceiling is 6,500 pounds.

Truck owners with standard fifth-wheel rails who need a gooseneck connection for heavy trailers can consider this plate. Keep both its 30,000-pound GTW rating and 6,500-pound vertical-load limit within the towing combination's requirements.

#4 · Best Rail Fit

4. HENTYMAX Gooseneck Ball Plate

• Compatible with Vehicle Type: Truck

Best for: Pin-secured standard-rail conversion.

Why it ranks #4: It fits industry-standard fifth-wheel rails and lists 30,000 pounds GTW, 7,500 pounds tongue weight, and four fixed pins.

Four included fixed pins make the HENTYMAX ball plate's installation method unusually concrete: it drops into industry-standard fifth-wheel rails and secures without drilling or permanent modification. The stated 30,000-pound GTW and 7,500-pound tongue-weight ratings give buyers two capacity limits to check for gooseneck hauling.

The standard-rail fit lets a truck owner convert an existing fifth-wheel rail system for gooseneck trailers, including livestock, flatbed, and equipment trailers. HENTYMAX specifies that the adapter is placed in the rails and secured with four included pins, so installation does not require drilling or permanent changes. Its 30,000-pound GTW and 7,500-pound tongue-weight ratings provide separate limits for evaluating a towing combination; those figures still need to align with the vehicle and trailer requirements.

Skip it if you need a specified 2-5/16-inch ball diameter; the labwork plate lists that size along with a 3-inch offset.

For owners converting standard fifth-wheel rails to tow livestock, flatbed, or equipment trailers, the pin-secured installation and stated capacity limits are useful specifics. The supplied listing does not give a ball diameter, so account for that fit detail.

5. MEPARERI Gooseneck Ball Plate

• Material: Metal
• Compatible with Vehicle Type: Trailer
• Weight: 16.83 kg

Best for: Livestock and equipment trailers.

Why it ranks #5: This standard-fifth-wheel-track plate is rated for 30,000 pounds GTWR and 7,500 pounds tongue weight, but converts rails to gooseneck.

A stated 30,000-pound maximum gross trailer weight rating makes the MEPARERI ball plate a candidate for heavy gooseneck hauling. It fits standard fifth-wheel tracks and is specifically presented for livestock and equipment trailers, converting an existing rail setup into a gooseneck towing point.

The universal standard-track fit is useful for a truck already equipped with fifth-wheel rails, since the plate provides a way to tow trailers with gooseneck tubes using that setup. Its listed 30,000-pound maximum GTWR gives buyers a capacity figure to check against their trailer and vehicle, while the separately stated 7,500-pound tongue-width figure should also be considered in the combination. The supplied details identify metal construction but do not describe installation hardware or removal workflow.

Skip it if you need an explicitly stated 2-5/16-inch ball; the CURT 16055 lists that ball size and a four-pin installation.

Choose this plate if your truck has standard fifth-wheel tracks and your gooseneck work includes livestock or equipment trailers. Check the listed GTWR and tongue-width figure against the vehicle and trailer requirements before towing.

6. CURT 16085 Spyder

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

Best for: Four-pin 25,000-pound towing.

Why it ranks #6: It converts industry-standard fifth-wheel rails to gooseneck and specifies a 25,000-pound rating, four-pin installation, and a 2-5/16-inch ball.

Four-pin installation and removal is central to the CURT 16085 Spyder's practical appeal, allowing a rail-equipped pickup to change its bed setup for gooseneck towing. It fits industry-standard fifth-wheel base rails, uses a welded 2-5/16-inch ball, and carries a stated 25,000-pound gross trailer weight rating.

The four-pin mounting system connects the Spyder to industry-standard fifth-wheel rails and supports removal for truck bed access, useful when the hitch is not needed. Its welded 2-5/16-inch ball provides the gooseneck connection, while the 25,000-pound gross trailer weight rating gives a clear capacity ceiling to check against the trailer and truck. The supplied details identify it for pickup trucks but do not state an offset option, so buyers seeking one should assess that requirement separately.

Skip it if you want a listed 3-inch rearward-offset position; the CURT 16055 offers that option by flipping the hitch.

The Spyder fits pickup owners who want to use standard fifth-wheel rails for gooseneck towing and value four-pin removal for bed access. Its listed capacity is 25,000 pounds, and no offset position is specified.

7. CURT 16055 Rail Adapter

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

Best for: Offset flexibility for rail-equipped trucks.

Why it ranks #7: This rail-mounted adapter has a welded 2-5/16-inch ball, 25,000-pound rating, and a 3-inch rearward offset option, but works in the reverse direction.

A reversible 3-inch rearward offset is the defining feature of the CURT 16055: position it over the axle or flip it to move the ball rearward. Its welded 2-5/16-inch ball and fit with industry-standard fifth-wheel base rails let a rail-equipped pickup switch to gooseneck towing.

The ability to place the hitch over the axle or flip it for a 3-inch rearward offset gives owners two ball positions to suit their towing setup. It mounts to industry-standard fifth-wheel base rails, and the four-pin installation and removal supports access to the truck bed when the hitch is taken out. The welded 2-5/16-inch trailer ball supplies the gooseneck connection, while its 25,000-pound rating sets the stated gross trailer weight ceiling.

Skip it if you need a stated 30,000-pound GTW rating; the MEPARERI Gooseneck Ball Plate lists that maximum capacity.

The CURT 16055 suits rail-equipped pickup owners who value a choice between an over-axle ball position and a 3-inch rearward offset. Its stated 25,000-pound rating is the boundary to observe when matching it to a trailer.

#8

8. labwork Gooseneck Hitch Plate

• Material: Alloy Steel
• Compatible with Vehicle Type: 5th Wheel Rails
• Weight: 18600 g

Best for: Three-inch-offset rail conversion.

Why it ranks #8: It fits standard fifth-wheel rails and lists a 25,000-pound GTW rating, 6,250-pound load, and 3-inch ball offset; it is reverse-direction.

A 3-inch ball offset from center is the labwork plate's key differentiator, giving rail-equipped trucks a defined rearward ball position for gooseneck towing. The listing pairs that offset with a 2-5/16-inch ball, a 25,000-pound gross trailer weight rating, and four fixed pins for installation and removal.

The 3-inch offset and 2-5/16-inch ball specify the connection geometry, while compatibility with standard fifth-wheel rails lets the plate serve trucks already fitted with that system. Four fixed pins support quick installation and disassembly, according to the listing, and the 25,000-pound GTW and 6,250-pound gross trailer weight figures provide stated limits to check. The 6mm steel construction and black powder coating are listed material and surface details for buyers considering the plate's use and upkeep.

Skip it if you need a listed capacity above 25,000 pounds GTW; the NUOVEPE plate is rated for up to 30,000 pounds.

Choose labwork if you need a defined 3-inch offset and a pinned plate for standard fifth-wheel rails. Its listed 25,000-pound GTW limit and 6,250-pound gross trailer weight figure should remain within the combination's requirements.

#9

9. 7BLACKSMITHS Ball Adapter Plate

• Material: Stainless Steel
• Compatible with Vehicle Type: Pickup Trucks, Trailer, Truck

Best for: Powder-coated replacement rail plate.

Why it ranks #9: Its 2-5/16-inch ball plate drops into existing fifth-wheel rails and is listed at 25,000 pounds, but it converts rails to gooseneck.

A black powder-coated stainless-steel plate that drops into existing fifth-wheel base rails gives the 7BLACKSMITHS adapter its defining combination of weather resistance and rail-based installation. It lets a pickup use those rails for gooseneck towing, with a 2-5/16-inch ball and a stated 25,000-pound capacity.

The drop-in fit for existing fifth-wheel base rails lets a pickup use one bed rail system for gooseneck towing, without the listing describing a replacement rail installation. Its 2-5/16-inch ball specifies the trailer connection, and the 25,000-pound rating provides a capacity figure to compare with the towing combination. The stainless-steel construction and durable black powder coat are presented for weather resistance; the supplied information does not list an offset, vertical-load limit, or pin details.

Skip it if you require a stated ball offset; the labwork 2-5/16 Inch Ball adapter specifies a 3-inch offset from center.

This plate fits pickup owners seeking a drop-in route from existing fifth-wheel rails to gooseneck towing, with a stated 25,000-pound rating. The listing does not state an offset or vertical-load limit, so those details may matter to fit selection.

#10

10. Nrovonis Gooseneck Ball Plate

• Weight: 32.3 lb

Best for: Standard-rail adapter option.

Why it ranks #10: The listing identifies a universal plate for standard fifth-wheel rails but provides no capacity or connection dimensions and serves the opposite conversion.

The Nrovonis plate is identified as fitting all standard fifth-wheel rails, giving owners of those rail systems a route to a gooseneck-ball connection. Its supplied listing also provides dimensions of 25 by 15 by 7.5 inches and a weight of 32.3 pounds, concrete details for handling and storage planning.

Universal fit for standard fifth-wheel rails is the central compatibility point, allowing the adapter plate to be considered by truck owners with that rail setup. The listed 25-by-15-by-7.5-inch dimensions and 32.3-pound weight can help buyers assess whether they have room to store and handle it when not in use. However, the supplied product information does not provide a towing-capacity rating, ball size, material specification, or installation procedure, limiting what can be verified from the listing.

Skip it if you need a stated 30,000-pound GTW rating; the HENTYMAX QQTT123 lists that capacity and a 7,500-pound tongue-weight limit.

Consider this Nrovonis plate if standard-rail compatibility and its listed dimensions are the main details you need. Buyers who must verify capacity, ball size, or installation steps from the product listing should note that those facts are not supplied.
