For high-horsepower GM LS-Series builds, the PAC Racing 1238X Dual Valve Springs are the ultimate choice. 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.
These springs are specifically engineered for builders who demand the highest level of performance from their LS engines. The dual-spring design provides a fail-safe mechanism while maintaining the necessary stiffness to handle high-lift cams. With a 0.985-inch coil bind, they offer excellent clearance for high-performance valvetrain geometry. Whether you are drag racing, road racing, or building a high-output street machine, these springs deliver the reliability and performance you need. Trust your high-performance engine build to the experts. Find all your specialized valvetrain components at GGCRACING.
