This Kit Turns Your Truck Into A Towing Machine

If you’re serious about towing, the B&W GNRM1016 Turnoverball Mounting Kit is a must-have upgrade for your 2016-2018 Silverado or Sierra 2500HD/3500HD with the 6.6L Duramax. This system gives you the muscle to handle gooseneck trailers with confidence, all while keeping your truck bed fully functional when the hitch isn’t in use. The genius is in the Turnoverball design, flip the ball over and it disappears below the bed surface, leaving you with a flat, unobstructed workspace. Whether you're hauling livestock, pulling a heavy equipment trailer, or setting off with a fifth-wheel camper, that 30,000 lb capacity has your back. It’s built for the kind of serious jobs that stock setups just aren’t meant for. What’s more, the install doesn’t require cutting into your frame, welding, or removing your bed. It bolts into existing holes, making it a clean and efficient way to boost your towing capability without butchering your truck.

Built Tough To Handle The Heaviest Loads

This B&W GNRM1016 kit is a vehicle-specific mounting system engineered to work seamlessly with 2016-2018 GM Silverado and Sierra 2500HD/3500HD trucks equipped with the 6.6L Duramax diesel engine. It installs underneath the truck bed using pre-existing holes in the frame, eliminating the need for any welding or frame modification. The only drilling required is a 4-inch center hole for the hitch ball and a few small holes for the safety chain hookups. At the heart of this setup is a 5/8-inch steel locking pin that goes all the way through the ball, secured by a spring-loaded mechanism and operated with a flexible latch handle for easy access. This design ensures a solid connection every time you tow. The mounting kit is part of B&W’s Turnoverball system, which lets you remove or flip the hitch ball when not in use to maintain full bed usability. Built from heavy-duty steel and proudly made in the USA, this kit delivers unmatched strength, reliability, and peace of mind when towing big loads.
