COMP Cams Valve Spring 1.539in Dual W/Da

These COMP Cams Elite Race Dual Valve Springs are built for demanding engine builds, especially those using roller cams. They're a popular choice for serious racing, including Dirt or Asphalt Late Model and Sportsman classes, and even some marine racing applications. They can also work in high-end flat tappet setups. The dual spring design offers improved stability and control over valve motion, which is crucial for handling higher valve lifts and preventing valve float at high RPMs. They are constructed with enhanced processing for good fatigue resistance, meaning they can handle the stress of repeated cycles in competition.

With an outside diameter of 1.539 inches for the outer spring and a .731 inch inside diameter for the inner spring, these are designed to fit specific cylinder head configurations. The springs are intended to be installed at a 2.000 inch installed height, which is a key measurement for ensuring they operate within their intended pressure range. This setup is well-suited for applications needing up to .750 inches of maximum valve lift, providing the necessary support to keep your valvetrain in check when you're pushing the engine hard.
