Description
Valve shims are critical to maintaining precise valve clearance and ensuring consistent engine performance across heat cycles. Over time, stock shims wear and degrade, leading to increased clearance deviation and potential valve train damage. The PROX Valve Shim 5-pack delivers precision-machined durability to restore exact specifications and keep your engine running at peak efficiency.
Each shim is manufactured using specialized heat-treatment processes that maximize hardness and resistance to wear, extending service life between adjustments. Whether you’re fine-tuning a high-revving race engine or maintaining a performance build, these shims provide the reliability and accuracy your valve train demands.
