Like our OEM puck system safety chain anchors, this gooseneck ball utilizes the factory towing prep package built into pickup trucks today. It features a quarter-turn latch lock for ease of use and a secure mount. Retention balls, built into the shank, keep the gooseneck ball fixed into the receiver hole. The standard 2-5/16 Inch ball has a gross trailer weight capacity of 35,000 Pounds. This particular OEM puck system gooseneck ball is compatible with Chevrolet, Ford, GMC and Nissan Titan XD pickups with the factory OEM puck system.
