About This Product
This S&S street performance valve spring kit is designed for Twin Cam engines and features conical round wire construction. These springs are capable of handling up to .585 inch of valve lift, making them suitable for a wide range of performance camshafts. The conical shape is specifically engineered to manage vibrations and reduce the overall mass of the valvetrain, which improves response and longevity. S&S manufactures these springs to strict tolerances to ensure uniform performance across all valves. This valve spring kit is sold as a set.
Manufacturer part number: 900-0594.
