16mm Bump Stop Shim 1/32in

The 16mm Bump Stop Shim 1/32in from Allstar Performance is a precision suspension component designed to fine-tune ride height and control bottoming resistance in high-performance automotive applications. This shim serves as a critical spacer element in bump stop assemblies, allowing technicians and tuners to adjust suspension geometry and compliance characteristics without replacing entire components. Whether you're optimizing a race car setup, restoring vintage suspension geometry, or dialing in a street performance build, this plastic shim provides repeatable, cost-effective geometry correction.

Manufactured in durable white plastic, the 16mm Bump Stop Shim features a 0.031-inch (1/32in) thickness and a 16mm shaft diameter, engineered to accommodate standard suspension mounting points found on most modern and classic automotive platforms. The plastic construction provides consistent performance across temperature ranges while resisting corrosion and chemical degradation common in underbody environments. Precision thickness tolerances ensure proper load distribution and prevent binding, allowing the suspension to compress and rebound smoothly through its intended travel range without premature bottoming.

This shim is ideal for suspension technicians, race engineers, and enthusiasts who demand precise control over vehicle dynamics. Installation is straightforward—simply position the shim between the bump stop assembly and its mounting surface, ensuring alignment with the 16mm shaft. The compact 4 x 0.15 x 7.1-inch profile fits easily in tight suspension bays, making it suitable for front and rear applications across diverse chassis designs. Use individually or in combination with additional shims to achieve exact suspension tuning specifications for your particular build.
