Jeep SJ Full Size Model 20 Rear Axles

Make Sure It Fits Your Vehicle

Your rig has proven reliable for your off-road adventures over the trails and the rocks and through the streams.

Any change you make to the rear axle should be done with strengthening the rear end in mind. Your classic Jeep is made for the long haul and meant to withstand the harshest, most severe conditions.
