Jeep Wrangler SJ Full Size Model 20 Rear Axle - Replacement Parts | 4WP

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. The Jeep is bound to take some knocks and dings along the way, and if the Model 20 rear axle is too bent, then you need to find the replacement parts before the damage keeps you from riding. 1980-91 SJs use the Model 20 axle and 4wheelparts.com has the parts you need to make repairs. 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.

Model 20 Replacement Parts
From nuts and gaskets to seals and bearings, 4wheelparts.com carries a variety of Jeep axle replacement parts so you can restore your rig back to its riding and handling glory. If your goal is to rebuild and set up, a ring and pinion installation kit has the pinion nut and seal, along with the bolts, shims, compounds and sealer needed to do the job. While you may be tempted to completely replace the axle, know that the Model 20 has a larger gear than more modern axles and holds up to tall tires, has strength and durability, handles heavy loads and takes on- and off-road abuse well.
