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 package includes the rear side extensions only. These two sides are intended to be mounted on the TrailChaser� rear bumper center section (sold separately). They offer a bold finishing touch with an aggressive cutout and mounting points for additional lights. These side extensions are constructed from T6 aluminum alloy to be strong, lightweight and rust-free, and have a unique, textured black powder coat finish for maximum corrosion resistance. They are also available in powder-coated steel.
