The ARIES TrailChaser� Jeep bumper is unlike any other bumper for the Jeep Wrangler JK because it features a modular design. Each piece can be attached or swapped out as desired, giving you complete freedom of customization. This particular bumper for the rear of the Jeep includes the center section and side extensions. It is constructed from T6 aluminum alloy to be strong, lightweight and rust-free, and has a unique, textured black powder coat finish for maximum corrosion resistance. It is also available in powder-coated steel. All ARIES TrailChaser� bumpers install using pre-existing factory mounting points for fast, easy installation with no drilling required.
