Fastened with u-bolts, spring plates clamp the leaf springs of your suspension system to the axle. As rugged as they are, these devices can and do wear out and must then be replaced. The good news is that they are relatively inexpensive and easy to install. We offer a wide array of Jeep Wrangler spring plates and degree shims for replacement, upgrade, or conversion. All of the parts we sell are made of high-quality materials that are specifically designed to withstand the rigors of off-road driving. Both spring plates and degree shims are used to provide stability and to correct the steeper angles of your drive shafts after a big lift.
