Description
Valve shim wear is a silent killer of engine performance—excessive clearance throws off your valve timing and costs you horsepower you’ve already paid for. PROX Valve Shims deliver precision-matched replacements at a fraction of OEM pricing, so you can dial in exact valve clearances without breaking the bank. These shims are heat-treated for hardness and longevity, meaning fewer replacements and more seat time between services.
