The CURT OEM puck system 5th wheel slider adapter for GM pickups combines the functionality of a CURT 5th wheel slider with the strength and convenience of GM's truck bed puck system. The adapter is designed to securely mount a CURT 5th wheel slider and hitch head into the bed of your Chevy or GMC truck, using the OEM puck system. It is designed to fit the puck system in select model years of the Chevrolet Silverado and GMC Sierra 2500 HD and 3500 HD with 6.5-foot bed (see application info to verify fitment) (compatible with CURT 5th wheel hitches only). 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. It features a capacity of 20,000 lbs. and is compatible with most CURT 5th wheel heads (weight capacities are limited to the lowest-rated towing component). Like our OEM puck system 5th wheel legs, the key feature of the GM 5th wheel slider adapter is its quarter-turn anchors. With the hitch head and slider 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 slider adapter for select Chevrolet and GMC pickup trucks provides the ultimate in versatility for the CURT 5th wheel line. With a gross trailer weight capacity of 20,000 lbs., it is able to accept most CURT 5th wheel sliders, including the R16 and R20. 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.
