16mm Shock Collar Shim Kit 3/4in 2pk

The ALLSTAR PERFORMANCE 16mm Shock Collar Shim Kit (ALL 64462) is a two-piece plastic collar-style shim assembly designed for 16mm shock absorbers. This kit provides precision spacing and alignment for suspension systems that rely on collar-mounted shock geometry, ensuring proper shock collar fitment and consistent damping response across suspension travel.

Each shim measures 3/4 inch in thickness and features a black plastic construction that resists corrosion and UV degradation. The collar-style design allows for straightforward installation without requiring modification to existing suspension hardware. Proper shim selection and installation are critical for maintaining shock preload and preventing metal-to-metal contact that could accelerate wear or compromise performance under load cycles. This two-pack configuration provides spares or allows users to dial in suspension geometry across multiple shock installations.

Technicians and operators working with 16mm shock systems—whether in off-road vehicle builds, competition suspension setups, or fleet maintenance—rely on quality shim kits to maintain consistent ride height and damping characteristics. Incorrect or degraded shims lead to misalignment, uneven load transfer, and reduced suspension responsiveness. ALLSTAR PERFORMANCE shock shims are engineered to OEM tolerance standards, ensuring repeatable fit and straightforward replacement during shock service intervals.

This kit is suited for anyone maintaining or upgrading suspension systems that call for 16mm shock collar shimming. Whether you're refreshing a worn suspension or building a new system from the ground up, having verified shim stock on hand prevents downtime and ensures specification-correct assembly.
