A CURT gooseneck hitch is more than a necessary tool for towing; it is an integrated extension of your truck that allows you turn your 4x4 into the workhorse it was designed to be. That is why CURT offers gooseneck hitch kits that include both the hitch and the installation brackets, making it simpler and easier to get your truck towing-ready. This kit includes the CURT Double Lock gooseneck hitch and installation brackets to match. The under-bed Double Lock gooseneck hitch gets its name from the two locking pins that engage the trailer ball and hold it in place, giving you twice the security when towing especially heavy trailers. The Double Lock mounts underneath your truck bed, using the included brackets, and provides a removable 2-5/16" gooseneck trailer ball with a gross trailer weight capacity up to 30,000 lbs. and a tongue weight capacity of 7,500 lbs. Using the heavy-duty operating handle, the trailer ball can be unlocked and flipped over whenever necessary to allow full use of the truck bed. The Double Lock comes with solid safety chain hookups, an attractive chrome trim ring, a durable carbide powder coat finish and a limited lifetime warranty. This particular Double Lock gooseneck hitch kit is design to be a custom fit for certain years of the Chevrolet Silverado 1500 or 2500LD with new body style or GMC Sierra 1500 or 2500LD with new body style (for a complete listing of vehicle and installation bracket compatibility, see the CURT application guide or visit curtmfg.com).
