1.538 Dual Valve Springs w/Damper (16)

The PAC RACING SPRINGS 1.538 Dual Valve Springs with Damper (16-piece set) is designed for serious engine builders and high-performance enthusiasts. This spring set is ideal for applications requiring enhanced valve control and reliability, such as street performance engines and classic muscle car restorations.

Engineered to handle aggressive valve timing and elevated RPM loads, these dual spring assemblies feature a 1.538-inch outer diameter and an integrated damper to manage harmonics and oscillation. The dual spring design provides progressive rate characteristics, allowing for lighter spring pressure at lower lifts while increasing force at higher lifts, which helps reduce parasitic drag on the camshaft.

These springs are particularly beneficial in high-performance applications where OEM valve springs may fail to meet the demands of modern performance engines. With precise manufacturing tolerances, the PAC Racing Springs ensure consistent preload and durability across the entire 16-piece kit, making them a reliable choice for eight-cylinder applications.
