Description
Valve shim wear directly impacts engine performance and reliability—whether you’re chasing lap times or maintaining precise valve clearance on a high-mileage build. PROX Valve Shims deliver OEM-equivalent precision at a fraction of the replacement cost, with proprietary heat-treatment that resists the micro-wear that degrades stock components. As a straightforward bolt-on replacement, they restore your engine’s valve train geometry without fabrication or special tools.
