How do I install this coil spring shim?

The shim mounts between the welded coil spring axle pad and the coil spring isolator on the front axle. The indexing pin on the isolator fits through the hole in the shim to ensure correct placement. Always refer to the manufacturer's installation instructions for detailed steps.

Can I stack multiple shims for more height adjustment?

Product Details

This is the RockJock front coil spring shim, designed for the axle side of your 2018-2025 Jeep Wrangler or 2020-2025 Jeep Gladiator. It's 3/16 inch thick and sits between the coil spring axle pad and the coil spring isolator.

These shims are useful for making small adjustments to your vehicle's ride height. This can be important to account for different engine options, added weight from accessories, or to achieve a specific stance. You can stack up to two of these shims if you need a bit more adjustment. The shim has a semi-gloss black powder coat finish for durability.
