Dual Valve Spring Kit

The COMP Cams dual valve spring kit provides a comprehensive solution for upgrading the valvetrain in GM LS-series engines. Each kit features precision-matched dual valve springs manufactured from Super Clean wire, paired with durable tool steel retainers, valve locks, Viton seals, and steel seats to ensure superior strength and reliability under demanding race conditions. Designed to handle high-performance applications, these springs accommodate a maximum valve lift of .650 inches and feature a spring rate of 400 lb/in. The 1.320-inch outer diameter springs are engineered to maintain consistent valvetrain stability, effectively managing the increased lift and stress common in extreme engine setups. Every component undergoes rigorous quality control testing to meet the high performance standards required by engine builders and competitive racing teams.
