Description
Shock shimming is fundamental to dialing in suspension geometry and controlling damping rates in racing applications. These Allstar Performance U-shaped shims allow you to fine-tune your shock valving stack without replacing entire cartridges—a cost-effective way to optimize performance across different track conditions and weight transfers. The 1/16″ thickness gives you precise incremental adjustments for both compression and rebound circuits.
Whether you’re running circle track, drag racing, or road course competition, having a full 25-pack on hand ensures you can experiment with stack configurations without downtime.
