The CURT OEM puck system 5th wheel adapter for Chevy, Ford and GMC pickups combines the functionality of CURT 5th wheel puck system products with the strength and convenience of the truck bed puck system. The adapter provides a set of industry-standard 5th wheel rails to securely mount a CURT 5th wheel hitch or roller into the bed of your truck. It is designed to fit select model years of the Chevrolet Silverado, GMC Sierra 2500 HD and 3500 HD and Ford F-250 and F-350 Super Duty (see application info to verify fitment). It features a set of adjustable, quarter-turn anchors to quickly and easily drop into the pucks and provide a moveable platform for the 5th wheel coupling point. This puck system adapter requires a specific puck system for installation (year range specific). It features a capacity of 25,000 lbs. and is compatible with all CURT 5th wheel legs and rollers (weight capacities are limited to the lowest-rated towing component). Like our other OEM puck system 5th wheel products, the key feature of the 5th wheel puck system adapter is its quarter-turn anchors. With the hitch initially bolted onto the adapter, the adapter can easily be dropped into place whenever needed and secured with the quarter-turn anchors. The anchors can also be adjusted to help eliminate chucking noises between the adapter and under-bed platform while towing. When you are finished towing, simply turn the anchors to remove the entire assembly within seconds. The CURT 5th wheel adapter for select Chevrolet, Ford and GMC pickup trucks provides the ultimate in versatility for the CURT 5th wheel line. It tested for safety in accordance with SAE J2638 and is coated in a highly durable carbide black powder coat finish to protect against scratches and rust.
