Valve Spring Shims 16pk 1.250 x .875 x .030

The Valve Spring Shims 16pk 1.250 x .875 x .030 from Howards Racing Components are precision spacers designed for high-performance engine builds where valve spring pressure and installed height control are crucial. These shims are essential for adjusting factory valve springs during modifications like cam upgrades or head porting, ensuring optimal valve seat pressure and spring resonance.

Each shim in this 16-pack features an outer diameter of 1.250 inches, an inner diameter of 0.875 inches, and a thickness of 0.030 inches, making them suitable for small-block and mid-sized engine platforms. The precise thickness allows for incremental adjustments in spring height, enabling builders to achieve the exact specifications required for their engine's valve train.

Performance enthusiasts, engine builders, and mechanics will benefit from these shims, as they provide the flexibility needed for multi-cylinder adjustments or future engine work. Manufactured to tight tolerances, these shims resist deformation under high-RPM loads, ensuring consistent performance across thermal cycles.
