The new Motobilt Crusher rear bumper for the JL was designed to work with a spare tire. This bumper was created to provide the most clearance possible while remaining completely bolt on. The Motobilt Jeep JL Crusher rear bumper has tons of clearance but we also added several other details. This bumper has been upgraded to include backup sensor cutouts to relocate your backup sensors into the Motobilt bumper. It also includes blank inserts if your Jeep is not equipped with proximity sensors.
