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 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. 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 2-5/16" and has a gross trailer weight capacity of 30,000 lbs. It also comes with a durable chrome finish and meets U.S. V-19 specifications for safety. This particular OEM puck system gooseneck ball is compatible with Ford and Ram pickups with the truck bed puck system. It can also be used in our OEM-compatible Ram hitches #60613 or #60614. It is not designed to fit any other gooseneck ball holes. The ball can be purchased as a standalone item or as part of a complete kit (#60609 for Ford and #60618 for Ram) that also includes the OEM puck system safety chain anchors, a rubber hole cover and a durable storage case.
