Fab Fours GM20-S5061-1 GMC Sierra 2500/3500 2020-2023 Black Steel Front Bumper With Sensor No Guard

Building the most premium materials, a talented engineering team, Fab Fours, has been the leader of the aftermarket industry since 2002. Because of its unique design, Fab Fours bumpers will give your truck a killer look the moment after you mount them. When you look closely at the bumper's surface, it's not hard to imagine how their experienced welders start welding their high-carbon premium steel in a clean modern factory.

For the GMC HD, we took the ranch bumper and gave it unique styling and design. We matched every bumper to the body lines of each model truck. With no vertical flanges and tapered edges. Available in either a Full Guard, Pre-Runner Guard, or No Guard bumper.

If you plan to build the most badass-looking truck in the world, then you must not miss these front and rear bumpers from the Fab Fours
