Product Details

Kelderman Manufacturing is proud to announce our all-new lineup of three-piece, modular bumpers for heavy-duty trucks. This bumper is designed for the 2020+ Silverado and Sierra 2500/3500HD trucks. Our 3 piece design allows for dozens of possibilities for customizing the color scheme to the truck and other accessories. The bumper has a main center section along with a pair of end caps or ‘wings’. A Kelderman rear bumper will have provided cutouts for a pair of 4″ E-Series lights to be integrated as a pair of extremely bright reverse lights. The rear bumper design also features a unique set of ‘pockets’ that provide a mounting point for aftermarket hooks, tow ropes, and other accessories. The 3 piece design allows you the opportunity to match the same color scheme on the front bumper or go another direction to add a bit more to your project. Parking sensor cutouts are also available. Available in raw metal finish, a textured black powder coat, or a primer powder coat. Bumper, lights, hooks, and other accessories are sold separately.

NOT COMPATIBLE WITH AT4X AEV trim level due to factory hitch interference.

CAUTION: Trucks Equipped with Parking Sensors, Adaptive Cruise, or Other Like Devices. The adaptive cruise control feature and factory-installed sensors, such as parking sensors, may not function properly when using any aftermarket bumper, including those manufactured by Kelderman Manufacturing, Inc.
