16mm Shock Collar Shim Kit 1/2in 10pk

The ALLSTAR PERFORMANCE 16mm Shock Collar Shim Kit in 1/2-inch thickness is an essential suspension tuning component for serious vehicle builders and mechanics who demand precision shock mounting. These shims help achieve perfect shock alignment and preload adjustment when factory mounts, frame rails, or custom brackets don't sit flush. This 10-pack ensures you have multiple shims on hand for both front and rear shock installations without interrupting your build schedule.

Each shim in this kit measures 16mm in diameter with a thickness of 1/2 inch, designed to fit various shock mounting applications. The shims work by filling gaps between the shock body and mounting bracket, allowing you to dial in ride height, load distribution, and correct any misalignment caused by chassis flexing or frame modifications. By stacking these shims strategically, you gain fine control over spring preload and shock positioning, which is critical for suspension geometry and handling balance.

This kit is ideal for independent suspension builds, double-wishbone conversions, and any coil-over or adjustable shock installation where precise adjustments are necessary. The compact, lightweight design makes transport and storage convenient, and the 10-piece quantity eliminates multiple supplier trips for a single build. Whether you're working on a drag car, street rod, or high-performance street machine, this shim kit is a valuable addition to your toolkit.
