The Addictive Desert Designs Stealth Fighter Tire Gate is an add-on to the Stealth Fighter rear bumper. The tire gate/bumper combination will hold up to a 40" spare tire. The main structure of the tire gate is constructed from a combination of 1/8" and 3/16" steel for strength and reliability. Spherical bearings are used as mounting points for additional strength and smooth operation. The Stealth Fighter tire gate swings open with the Jeep's JK tailgate and allows for full use of the tailgate with no restriction. This product is fully bolt-on and made in America.
