About this kit
50-Inch Curved Light Bar Windshield Mount, fitment-checked
Rough Country 70513A is an upper-windshield mount for a 50-inch curved LED light bar on 2015-2019 Silverado 2500 HD/3500 HD and Sierra 2500 HD/3500 HD trucks in 4WD and RWD. It carries a black powder-coated finish and accepts single-row or dual-row curved bars sized 50 inches between mounting points, with 8mm posts. Drilling is part of the install, and the light bar is a separate purchase.
This upper-windshield mount holds a 50-inch curved LED light bar on 2015-2019 Chevrolet Silverado 2500 HD and 3500 HD and GMC Sierra 2500 HD and 3500 HD models, including a 2015 Silverado 3500 RWD application. Check your bar before ordering: the brackets are cut for curved bars only, measured 50 inches from mounting point to mounting point, using 8mm posts. Rough Country's 72950 dual-row and 72750 single-row curved bars both match those figures. Rough Country lists 1-2 hours for the job, drilling included, and a downloadable installation guide is available.
