The CURT OEM puck system 5th wheel roller adapter for GM pickups combines the functionality of a CURT 5th wheel roller with the strength and convenience of GMs truck bed puck system. The adapter is designed to securely mount a CURT 5th wheel roller and hitch head into the bed of your Chevy or GMC truck, using the OEM puck system (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. This puck system roller adapter is specifically designed for short-bed trucks and requires the GM puck system for installation. 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 roller adapter is its quarter-turn anchors. With the hitch head and roller 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 roller adapter for 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 rollers, 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. We also give the OEM puck system 5th wheel roller adapter a limited lifetime warranty to make sure it can keep up wherever you and your GM truck wander (warranty does not carry over to any other 5th wheel components or attachments).
