1.265 Valve Spring Kit Single w/Damper

The 1.265 Valve Spring Kit Single with Damper from HOWARDS RACING COMPONENTS is designed for serious engine builders and high-performance enthusiasts who require precise valve control at high RPMs. This single valve spring assembly is suitable for both forced-induction and naturally aspirated applications, addressing the limitations of stock springs in managing aggressive valve acceleration and preventing valve float.

Engineered with a 1.265-inch outer diameter, this spring features an integrated damper that minimizes harmonic oscillation and surge within the valve train. This design is crucial for preventing premature spring failure and maintaining seat pressure under demanding conditions. Manufactured to tight tolerances using premium alloy steel, these springs ensure consistent spring rates across the compression range and reliable performance across varying engine loads and temperatures.

Ideal for mechanics and engine builders, this kit should be verified for compatibility with specific cylinder heads and valve diameters. Whether you're building a street performance engine or preparing for track use, this valve spring kit is essential for achieving modern power goals in classic restorations.
