PSAUTO Cushioned Gooseneck Adapter
The cushioned gooseneck adapter converts your 5th wheel into a gooseneck in minutes. Best for buyers who want a quick, comfortable transition without tools. This model emphasizes a cushioned connection to reduce metal-to-metal wear during towing. It is suitable for lighter-to-midweight setups where a cushioned interface is preferred. A potential limitation is absence of a published weight rating in the listing, so verify compatibility with your trailer and hitch system before use.
GEARBONE 5th Wheel to Gooseneck Adapter 15-21 in
Best for heavy-haul RVs and trailers that require robust steel and quick, tool-free setup. This GEARBONE adapter uses 1/2″ thick steel and supports up to 30,000 lbs GTW, with an adjustable range from 15″ to 17″ and pre-drilled holes with grade-8 bolts for a fast installation. It fits standard gooseneck couplers with a secure 3/4″ retainer pin. Choose this if you prioritize high capacity and straightforward installation; avoid if your mounting space is irregular or you have a shallow bedliner that might interfere with installation.
BaVekHak 5th Wheel to Gooseneck Adapter
Best for users needing a broad height range and strong capacity. The 15″ to 21″ adjustable range supports diverse truck configurations, and the unit is rated for 30,000 lbs GTW. It features a self-centering locking plate to ease hitching and improve security. A potential limitation is the need to confirm your exact vehicle and trailer height to ensure exact leveling before locking. Use this when precise leveling matters most in your setup.
GEARBONE 15-17 Inch Adapter
Best for mid-height applications where quick tool-free setup is valuable. This GEARBONE unit provides a 15″ to 17″ adjustable range and a 30,000 lbs GTW rating. It’s compatible with standard gooseneck couplers and includes pre-drilled holes with grade-8 bolts for faster installation. Choose this if you want a compact, robust option; avoid if your trailer requires a taller clearance beyond 17 inches.
CURT 16310 X5 Fifth Wheel Adaptor Plate
Best for compatibility across a variety of gooseneck and fifth-wheel hitch systems. The X5 adapter enables towing of both gooseneck and 5th wheel trailers by dropping into standard gooseneck hitches and providing industry-standard rails. It’s tested to tow up to 20,000 lbs gross trailer weight and is not compatible with turret-style pin boxes. Factory or aftermarket bedliners can interfere with install; ensure your hitch and bed design match before purchasing.
FlexHitch Fifth Wheel to Gooseneck Adapter
Best for a simple, practical conversion without bed welding or modification. The FlexHitch supports up to 30,000 lbs and includes anti-tilt washers plus a 5th-wheel lube plate to reduce friction and wear. This combination helps prevent tilting and improves stability during stops. A limitation is the need to ensure the washers stay in place during heavy braking; verify proper installation and periodic checks for secure operation.
Fexhull 5th Wheel Hitch to Gooseneck Ball Adapter
Best for tractor-trailer fifth wheels and heavy-duty use with its forged 2-5/16″ ball and 30,000 lbs rating. Fits a range of OE and aftermarket configurations. The design emphasizes a solid kingpin coupling with a bolster, providing reliable connection. A caution is to confirm compatibility with your specific kingpin and hitch plate; not all systems will accept every kingpin type.
Buying Guide
Height range and capacity matter most. Align the adapter’s range with your truck bed and trailer height to maintain level towing and avoid contact with the truck bed or trailer overhang.
Material and construction influence durability. Steel thickness (commonly 1/2″) and overall weight-bearing capacity determine long-term reliability for heavy trailers.
Installation and compatibility are key. Look for tool-free setup or simple bolt-on designs if you want quick changes. Check bedliners, turret pin boxes, and your gooseneck hitch model for interference issues.
Locking and alignment features affect safety. Self-centering plates and anti-tilt washers improve alignment and reduce movement during braking or sharp turns.
Versatility vs. simplicity. Some adapters are single-purpose, others support dual configurations. Decide whether you want the flexibility to switch between gooseneck and 5th wheel towing frequently or a dedicated solution.
