Outfitting your pickup to tow a heavy-duty flatbed or livestock trailer is easy with the CURT OEM puck system gooseneck ball. Like our OEM puck system safety chain anchors, this 38K gooseneck ball utilizes the puck system built into certain pickup trucks today with the towing prep package. It features a patented installation system, operating with a simple quarter-turn latch lock for ease of use and a secure mount. Stainless steel retention balls, built into the shank, keep the gooseneck ball fixed into the receiver hole and keep your trailer locked on tight. It provides a ball diameter of 3" and has a gross trailer weight capacity of 38,000 lbs. It also comes with a durable chrome finish and meets J2638 specifications for safety. This particular OEM puck system gooseneck ball is compatible with Chevrolet, Ford, GMC, Nissan Titan XD and Ram pickups with the truck bed puck system. It is not designed to fit any other gooseneck ball holes.
