Designed for the RPM Series, these springs feature a robust 600 lb/in spring rate, providing the necessary pressure to control aggressive camshaft profiles and high-RPM operation. The dual-spring configuration ensures maximum durability and harmonic stability, preventing valve float and protecting your engine internals.
