1.260 Single Valve Springs w/Damper (16)

The 1.260 Single Valve Springs w/Damper (16) are engineered for high-performance circle track applications where valvetrain stability is critical at elevated RPM ranges. These PAC Racing 1200 Series components provide the necessary tension to prevent valve float, ensuring consistent timing and engine longevity during competitive racing sessions. Designed specifically for builders seeking a reliable single-spring solution, this set of sixteen springs offers a precise fit for cylinder heads requiring a 1.260-inch outer diameter.

Each spring in the 1.260 Single Valve Springs w/Damper (16) set features an integrated damper to suppress harmonic vibrations that can lead to premature valvetrain failure. With a robust spring rate of 540 lb/in, these springs manage aggressive camshaft profiles while maintaining a coil bind height of 1.115 inches to allow for sufficient lift clearance. The use of advanced metallurgy in the 1200 Series ensures that the springs maintain their load over time, resisting the heat soak common in endurance racing environments.

Professional engine builders and enthusiasts can rely on the 1.260 Single Valve Springs w/Damper (16) for various circle track engine platforms that utilize a single-spring configuration. Proper installation requires verifying the installed height and retainer compatibility to maximize the 540 lb/in rate and prevent coil bind issues. This complete set of 16 springs provides a uniform upgrade for a full V8 valvetrain, offering a significant performance improvement over standard OEM components when searching for specifications and reliability.
