Description
Valve shim wear is one of the most common causes of valve train noise and performance loss in high-revving engines. These PROX shims deliver precision fitment and heat-treated durability at a fraction of OEM replacement costs, making them the smart choice for both track maintenance and street builds. Stock shims wear faster than you’d expect—keep a pack on hand and avoid costly downtime between sessions.
