#1 · Best Overall

1. Lamerto C5G1216

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

Best for: Height-adjustable cushioned RV towing.

Why it ranks #1: Direct kingpin conversion, cushioned construction, 12-to-16-inch adjustment, 20,000-pound rating, and included safety chain make this a well-specified match.

A sliding collar adjusts from 12 to 16 inches, letting this Lamerto adapter set the connection height between a fifth-wheel kingpin and a gooseneck hitch. Its built-in cushioning is intended to reduce shock and vibration while towing, while the included safety chain adds a separate safety connection for compatible camper, RV, and trailer setups.

The 12-to-16-inch height range gives owners room to set the kingpin-to-ball connection for their towing configuration, and set screws lock the sliding collar at the selected height. The cushioning structure addresses shock and vibration on the road, with the stated aim of protecting both the trailer kingpin and gooseneck hitch. It mounts directly to the kingpin, and verified product information says conversion takes minutes without drilling or welding. The stated gross trailer weight capacity is 20,000 pounds.

Skip it if you need a stated capacity above 20,000 pounds; this adapter's published gross trailer weight rating is 20,000 pounds.

This Lamerto suits RV and camper owners converting a kingpin trailer to a gooseneck while needing adjustable height and cushioning. Keep its 20,000-pound gross trailer weight rating and 12-to-16-inch range in mind when assessing the setup.

#2 · Height-Adjustable Pick

2. Weonefit C5G1216

• Material: Alloy Steel, Metal
• Weight: 27.6 kg

Best for: Cushioned adapter for longer beds.

Why it ranks #2: Direct kingpin adapter adjusts from 12 to 16 inches and is rated for 20,000 pounds GTW and 4,000 pounds pin weight; it flags fit limits.

A sliding collar with set screws provides Weonefit’s C5G1216 with adjustment from 12 to 16 inches, while cushioning and a safety chain address towing movement and connection security. It is rated for 20,000 pounds towing and 4,000 pounds pin weight, with explicit fit cautions for short truck beds and cushioned-style kingpin boxes.

The height range allows adjustment within four inches, and the sliding collar’s set screws hold the selected position. The cushioned construction is paired with a safety chain, offering both movement absorption and a separate safety connection in the listed setup. Weonefit specifies a 20,000-pound towing capacity and 4,000-pound pin weight capacity. Its fit guidance is especially important: the product is not recommended for truck beds shorter than six feet or for cushioned-style kingpin boxes, so those configurations are clear exclusions.

Skip it if you have a truck bed shorter than six feet or a cushioned-style kingpin box; Weonefit explicitly excludes those setups.

The Weonefit C5G1216 suits owners with compatible camper, RV, or trailer kingpin boxes who want adjustable height, cushioning, and a safety chain. Avoid it for beds under six feet or cushioned-style kingpin boxes.

#3 · Cushioned Ride Pick

3. Convert-A-Ball C5G1216

• Weight: 67 lb

Best for: Bounce-conscious fifth-wheel owners.

Why it ranks #3: This direct adapter is rated for 20,000 pounds GTW and 4,000 pounds pin weight, with poly cushions listed to reduce bounce and vibration.

Poly cushions absorb shock in the Convert-A-Ball C5G1216, addressing bounce and vibration as it adapts a fifth-wheel trailer to a gooseneck hitch. Adjustable height supports multiple applications, while the stated 20,000-pound gross trailer weight and 4,000-pound pin weight capacities set clear load boundaries for choosing this cast-steel adapter.

The adjustable-height design can serve multiple applications, while poly cushions absorb shock to help reduce bounce and vibration during towing. Convert-A-Ball also states that the design minimizes wear and tear on both trailer and vehicle, a relevant consideration for owners making this connection regularly. Cast-steel construction and a 20,000-pound gross trailer weight capacity define its build and towing limit; the listed pin weight capacity is 4,000 pounds. The supplied facts give no specific adjustment range, so buyers should not assume a particular height span.

Skip it if you need a confirmed numeric height range before choosing; this listing says adjustable but gives no range.

This Convert-A-Ball suits fifth-wheel owners prioritizing shock absorption and adjustable application height within its stated load limits. Because the supplied listing does not give a numeric adjustment span, that detail matters when matching a particular truck and trailer.

#4 · 360-Degree Cushioning

4. GELUOXI C5G1216

Why it ranks #4: A direct kingpin adapter with 12-to-16-inch adjustment, 20,000-pound GTW capacity, 4,000-pound tongue weight, and listed 360-degree cushioning.

GELUOXI’s adapter combines 12-to-16-inch height adjustment with cushioning in every direction, including up-and-down movement, to connect a trailer kingpin to a gooseneck hitch. The stated 20,000-pound gross vehicle weight capacity and 4,000-pound tongue weight capacity give buyers concrete limits for evaluating a compatible towing setup.

A sliding collar and set screws allow height adjustment from 12 to 16 inches, helping match the adapter to the connection height needed for a trailer and truck. Its 360-degree cushioning plus vertical movement is intended to absorb movement during towing rather than leave the connection entirely rigid. The product is specified to convert a trailer kingpin for a gooseneck hitch and includes safety chains. Buyers should assess both its 20,000-pound gross vehicle weight and 4,000-pound tongue weight limits for their load.

Skip it if you need a stated gross vehicle weight capacity above 20,000 pounds; this GELUOXI adapter is rated to that limit.

The 12-to-16-inch adjustment offers a range for setting the connection height between the trailer kingpin and gooseneck hitch, which can help match different towing configurations. Its 20,000-pound towing capacity and 4,000-pound maximum vertical pin weight define separate limits to check against the load. The adapter is described as durable steel and is listed for trailer compatibility. Factory testing is stated in the product information, but installation method and included safety-chain details are not specified in the supplied facts.

#6 · Highest Capacity

6. YEOPGYEON Adapter Hitch

• Material: Carbon Steel
• Compatible with Vehicle Type: RV, Truck

Best for: Heavy-load adjustable-height towing.

Why it ranks #6: Its direct-adapter title and 15-to-21-inch settings suit taller configurations, while the listed 30,000-pound GTW rating leads this selection.

A 30,000-pound gross trailer weight rating paired with four selectable heights makes the YEOPGYEON adapter suited to buyers matching a heavy trailer to varied truck-bed heights. Its 15-, 17-, 19-, and 21-inch settings provide defined positioning choices, and the 2-5/16-inch ball fit specifies the gooseneck connection.

The four height settings—15, 17, 19, and 21 inches—let an owner choose among defined positions to level a trailer for different truck-bed heights and towing configurations. The product states that this can improve ride stability and control. Reinforced Q235 steel construction accompanies the 30,000-pound gross trailer weight rating, giving a material and capacity basis for evaluating heavier use. Its universal 2-5/16-inch gooseneck ball fit is another compatibility check; height selection is preset rather than continuously variable in the supplied specifications.

Skip it if you need continuous height adjustment between settings; this YEOPGYEON model lists four positions: 15, 17, 19, and 21 inches.

This YEOPGYEON adapter suits owners of large RVs, campers, or heavy trailers who need a 30,000-pound rating and defined height choices. Confirm that one of its four settings and the 2-5/16-inch ball fit the setup.

#7

7. Misakomo Kingpin Adapter

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

Best for: Forged-steel kingpin conversion.

Why it ranks #7: This forged-steel, one-piece kingpin-to-ball adapter directly addresses the conversion, and its listed ball size is 2-5/16 inches.

One-piece machined forged steel is the defining feature of the Misakomo kingpin-to-gooseneck adapter, with the product describing force distribution and resistance to breakage as benefits of that construction. A protective coating is specified for rust resistance, and the adapter uses a 2-5/16-inch ball with a 2-inch kingpin size.

The one-piece forged-steel construction and machining are presented as ways to distribute force uniformly through the adapter, while the protective coating is intended to resist rust in severe weather. Its listed 2-inch kingpin size and 2-5/16-inch ball identify the connection dimensions buyers need to match. Compatibility is listed for trucks, tractors, and trailers. The supplied product details do not state a towing-capacity figure or height adjustment range, so the stated construction and dimensions should not be mistaken for a load rating.

Skip it if you need a stated load rating or adjustable height; the supplied Misakomo specifications give neither figure.

The Misakomo adapter suits buyers whose kingpin and gooseneck ball match its listed 2-inch and 2-5/16-inch dimensions and who value coated forged steel. The supplied details do not provide a capacity or height range.

8. CURT 16055

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

Best for: Quick-change fifth-wheel rail users.

Why it ranks #8: A rail-mounted alternative for trucks with standard fifth-wheel rails, it has a 25,000-pound rating, welded 2-5/16-inch ball, and 3-inch offset.

Four-pin installation and removal let the CURT 16055 switch a truck with industry-standard fifth-wheel rails to gooseneck towing, then clear the bed for other use. Its welded 2-5/16-inch ball serves a gooseneck connection, and the plate can sit over the axle or flip for a three-inch rearward offset.

This rail-mounted hitch is for pickup trucks already equipped with industry-standard fifth-wheel base rails, so the conversion does not call for replacing that rail setup. The four-pin attachment makes removal straightforward when bed access is needed, while the welded 2-5/16-inch ball provides the trailer connection. Positioning over the axle or flipping the plate for a three-inch rearward offset gives two placement choices. Its stated capacity is 25,000 pounds; it is a rail adapter, not a kingpin-mounted cushioned coupler.

Skip it if you need to convert a trailer kingpin directly or want a height-adjustable cushioned coupler; this is a rail-mounted plate.

Choose the CURT 16055 if your pickup already has standard fifth-wheel rails and you want a removable gooseneck connection with an offset option. Its rail dependence and fixed plate format make it a different solution from kingpin-mounted adapters.

9. CURT 16085 Spyder

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

Best for: 25,000-pound rail adapter users.

Why it ranks #9: This rail-mounted gooseneck adapter fits industry-standard rails and lists a 25,000-pound GTW rating with a welded 2-5/16-inch ball.

A welded 2-5/16-inch ball and a 25,000-pound gross trailer weight rating make the CURT 16085 a rail-mounted route from fifth-wheel towing hardware to gooseneck towing. It fits industry-standard base rails and uses four-pin installation and removal, helping owners switch towing modes and regain truck-bed access.

The Spyder mounts to industry-standard fifth-wheel base rails, so it suits a truck that already has that hardware rather than a trailer kingpin that needs a direct coupler adapter. Four-pin installation and removal simplifies taking the unit out when bed access matters. Its welded 2-5/16-inch ball provides the gooseneck connection, and the stated 25,000-pound gross trailer weight rating defines its capacity boundary. The supplied specifications identify carbide material, but no height adjustment or cushioning is specified.

Skip it if you need a kingpin-mounted adapter with adjustable height or cushioning; this CURT plate mounts to truck-bed rails.

The CURT 16085 fits pickup owners with standard fifth-wheel rails who need a removable 25,000-pound-rated gooseneck plate. Consider the rail-based installation and the stated 2-5/16-inch ball when matching it to your truck and trailer.

#10

10. NUOVEPE Hitch Plate

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

Best for: Higher-capacity standard-rail towing.

Why it ranks #10: Its 30,000-pound GTW and 6,500-pound vertical-load ratings are substantial, but it converts standard fifth-wheel rails rather than attaching to a kingpin.

A 30,000-pound gross trailer weight rating distinguishes the NUOVEPE gooseneck hitch plate for owners converting standard fifth-wheel rails for heavier towing applications. Its 6,500-pound maximum vertical load and 2-5/16-inch ball provide additional capacity and connection details, while universal compatibility with standard rails keeps the installation tied to an existing rail system.

This plate fits standard fifth-wheel rails, allowing a pickup already using that system to connect to a gooseneck trailer without changing the rail format. The heavy-duty hardened steel construction accompanies a stated 30,000-pound gross trailer weight rating and 6,500-pound maximum vertical load, useful figures when matching equipment to a demanding haul. The 2-5/16-inch ball specifies the trailer connection. Its stated application examples include dump, boat, farm, and other gooseneck trailers; the supplied information does not describe height adjustment or cushioning.

Skip it if you need a kingpin-mounted adapter or adjustable cushioning; this NUOVEPE product is a fifth-wheel rail plate.

The NUOVEPE plate suits truck owners with standard fifth-wheel rails who need a gooseneck connection and the stated 30,000-pound capacity. Its rail-based format and 2-5/16-inch ball are the key fit considerations for a particular truck and trailer.
