16mm Shock Shim U-Shaped 1/16in 10pk

The Allstar Performance 16mm Shock Shim U-Shaped 1/16in 10-pack is a precision suspension tuning component designed for adjusting shock absorber preload and ride height on performance vehicles. These lightweight plastic shims are engineered to work specifically with 16mm shock applications, allowing technicians and enthusiasts to fine-tune suspension geometry without replacing entire shock assemblies.

Each shim measures 1/16 inch thick and features a U-shaped profile that seats securely around shock bodies. The yellow plastic construction provides excellent chemical resistance and dimensional stability under thermal cycling—critical when working with suspension components exposed to heat and oil vapor. The 10-pack format ensures sufficient material for front and rear applications, with extras for testing different preload heights during setup tuning.

Track builders, chassis specialists, and suspension technicians rely on shock shims to dial in vehicle handling characteristics without breaking down shock units. Stacking shims adjusts spring preload, which directly influences ride height, spring rate feel, and suspension compliance. This 16mm shim pack is essential for anyone working on independent front suspension systems or performance builds that require shock adjustment capability.

Allstar Performance is recognized in the racing and fabrication community for producing cost-effective suspension components that hold tight tolerances. These shims are a consumable part for shops performing regular suspension work—replacements wear or get lost during reassembly, making a full 10-pack practical for both one-time tuning jobs and ongoing inventory.
