Valve Disc Kit 8pk .542 OD X .015in

The Valve Disc Kit 8pk .542 OD X .015in from QA1 is a precision component designed for high-performance valve train systems. It is particularly useful in competition and modified engines where precise clearance control is essential. This kit allows for tuning valve lift and lash in adjustable rocker arm assemblies, making it an invaluable tool for performance builders and mechanics.

Each shim-style disc in the kit features a .542-inch outer diameter and a .015-inch thickness, enabling micro-increments of valve adjustment. The discs are designed to stack and layer within rocker arm assemblies, ensuring they fit seamlessly into tight valve cover spaces. This thoughtful design is critical for achieving optimal valve geometry and preventing valve binding issues during engine assembly.

Engine builders, machine shops, and serious DIY mechanics will find this valve disc kit essential for working with adjustable rocker systems on small-block and mid-sized engines. The eight-pack quantity provides multiple adjustment options, allowing users to dial in their engine's performance without the need to replace entire valve train components. QA1's commitment to quality ensures consistent material composition and flatness across the kit, reducing the risk of premature wear.
