Less Weight = Better Fuel Economy: Rugged Ridge XHD Aluminum Bumper System for Jeep Wranglers JK. Designed to be a whole new look while being extremely light weight. Save on fuel and the environment.

If you want to run a winch, simply remove the filler plate and attach the optional JK Winch mounting plate (Steel Plate).The XHD Aluminum bumper is approximately 80lbs+ lighter than the average steel off road bumper.
