16mm Shock Shim U-Shaped 3/8in 25pk

The Allstar Performance 16mm Shock Shim U-Shaped 3/8in 25-Pack (ALL64454-25) is a precision tuning component designed for mechanics and suspension builders specifically working with coilover systems and drag racing applications. These shims are essential for fine-tuning damping rates to match your vehicle's weight transfer and spring rates, ensuring optimal performance on the track.

This 25-piece pack allows for multiple shims per rebuild cycle, enabling you to adjust compression and rebound characteristics effectively. The U-shaped design is intended to provide flexibility in tuning without the need for complete shock assembly replacements. While they do influence damping resistance, their primary role is to facilitate adjustments in suspension tuning.

Track-focused builders, autocross competitors, and street performance enthusiasts will find these shims beneficial during suspension development. Whether you're tuning for a road course or optimizing drag racing geometry, having multiple shims on hand can significantly enhance your build process and reduce downtime.
