CURT OEM puck system 5th wheel legs allow for faster, easier and more secure installation of your CURT 5th wheel hitch. They utilize the truck bed mounting platform, called the puck system, built into certain pickups today with the towing prep package. Using a set of anchors, the legs quickly and easily drop into the pucks, instantly equipping the truck for 5th wheel towing. This set of 5th wheel legs is designed to fit select Chevrolet or GMC trucks with the puck system and cannot be installed without it (year range specific). With a gross trailer weight capacity of 30,000 lbs., the legs are compatible with the CURT A30 5th wheel hitch head #16590, A25 #16580 or A20 #16540 (weight capacities are limited to the lowest-rated towing component). The most unique feature of CURT OEM puck system 5th wheel legs is their quarter-turn anchoring system. This system is the key to streamlined 5th wheel towing. With the hitch head initially bolted onto the legs, the legs can quickly be installed or removed from the truck bed as needed, simply by turning the anchor handles. The quarter-turn anchors supply the necessary strength for towing heavy-duty 5th wheel trailers, and they feature an adjustable design to perfectly lock the hitch into place and eliminate any chucking noises. To give you confidence in every job you undertake with your truck, we give our OEM puck system 5th wheel legs a durable carbide black powder coat finish. This makes them highly resistant to scratches, rust and UV damage. We also back our 5th wheel legs with a limited lifetime warranty to put your mind at ease with every new mile.
