Isky Racing Cams Valve Springs

Isky Racing Cams valve springs are performance engine valve springs (also called racing valve springs or high-performance valve springs). They are built to control valve motion in modified street, drag, circle track and other competition engines. Isky has been a well-known name in camshaft and valvetrain design since the 1930s, and this line carries that racing experience into its spring designs.

Key Features:

• Designed to keep the valve following the cam lobe accurately at high RPM, which helps prevent valve float
• Matched to Isky camshafts and valvetrain components for a balanced, dependable setup
• Built for the higher spring loads and lift that performance cams need
• Several spring styles and rates are offered across the line to suit different engine builds and cam profiles
• Made for durability under repeated, high-stress cycling in racing use

Pair these springs with the right retainers, locks and hardware, and check installed height and coil bind clearance during assembly. Choose the spring that matches your camshaft's lift and intended use. Isky valve springs help engine builders get consistent valvetrain control and reliable power from a performance build.
