Ingenious design and reliability -- these words don't just describe the Chevrolet Silverado and GMC Sierra 2500 HD and 3500 HD; they were the inspiration for the CURT OEM-style gooseneck hitch for GM. This hitch is built to excel in two key things: ease of installation that comes from an ingenious design and safe, reliable towing even with heavy-duty gooseneck trailers. The Chevy / GMC-compatible gooseneck hitch boasts a one-person installation. It is built with fewer pieces than competitor hitches to keep installation simple, and the pieces are designed to be compact so they can be lifted and bolted into place without the help of a second person. We've also eliminated a number of steps from the process to speed up installation time and reduce the number of modifications needed on the vehicle. The hitch does not require the exhaust or spare tire to be lowered. It requires no welding, temporary truck bed removal or even bed flange trimming. Best of all, pre-existing factory holes are used to mount the hitch to the truck's frame, meaning the only drilling necessary is for the gooseneck ball hole and safety chains in the truck bed. Once installed, the OEM-style gooseneck hitch for Chevrolet / GMC offers simple operation and highly secure towing. It is tested in accordance with SAE J2638 to safely tow up to 32,500 lbs. GTW. Instead of a side handle mounted under the wheel well, it uses a latch-locking trailer ball. This patented 2-5/16" ball easily drops into the gooseneck head from above the truck bed and is secured in place with a simple quarter-turn of the latch. This Chevrolet Silverado / GMC Sierra 2500 HD and 3500 HD gooseneck hitch also features heavy-duty 5/8" safety chain anchors for dependable security for your trailer, whether you're towing livestock, machinery or construction materials. To ensure maximum quality, the CURT OEM-style gooseneck hitch for GMC and Chevrolet comes with a tough A-coat finish to easily resist rust and scratches.
