Valve Spring Shims 16pk 1.250 x .875 x .060

The Valve Spring Shims 16pk 1.250 x .875 x .060 from HOWARDS RACING COMPONENTS are precision-engineered steel shims designed for engine builders and performance mechanics who need to fine-tune valve spring pressure and installed height. These shims allow technicians to adjust spring preload and correct seat height variations during engine assembly or rebuild work.

Each shim in this 16-pack measures 1.250 inches in outer diameter with a 0.875-inch inner bore and 0.060 inches in thickness. The steel construction provides the rigidity needed to maintain consistent valve spring pressure under high-rpm operation. Valve spring shims function by stackable design—multiple shims can be combined to achieve the exact installed height required by your engine's specifications. This precision thickness tolerates less variance than standard washers, critical for maintaining proper spring rates and preventing valve float in performance or racing applications.

These shims are essential for serious engine builders, racing teams, and automotive shops performing complete cylinder head work. Whether you're building a street performance engine, preparing for track use, or restoring a classic with upgraded valvetrain components, maintaining correct installed spring height directly impacts valve control, fuel efficiency, and engine longevity. The 16-piece quantity supports multiple cylinders or provides spare shims for future adjustments.

HOWARDS RACING COMPONENTS is recognized for producing OEM-quality and racing-grade engine components. Valve spring shims must meet strict dimensional standards to ensure they stack flat and deliver predictable results—any variability compounds across multiple cylinders and can cause uneven spring loads, leading to valve control issues at high rpm.
