The ARIES TrailChaser Jeep bumper is unlike any other bumper for the Jeep Wrangler JK because it features a modular design. This particular bumper for the rear of the Jeep includes the center section and side extensions. It is constructed from high-strength carbon steel and has a unique, textured black powder coat finish for maximum rust resistance. It is also available in powder-coated aluminum. All ARIES TrailChaser bumpers install using pre-existing factory mounting points for fast, easy installation with no drilling required.
