Engineered for Maximum RPM

The PAC Racing RPM Series Beehive Valve Springs are designed for high-performance applications where valve control is critical. These beehive springs offer a significant improvement over factory components, providing the spring rate necessary to support aggressive camshaft profiles without sacrificing longevity. The unique beehive geometry effectively manages harmonics, allowing your engine to rev higher and faster with confidence.

Key Features

  • Spring Rate: 313 lb/in
  • Outside Diameter: 1.290 in
  • Coil Bind: 1.140 in
  • Application: High-performance street and strip
  • Set of 16 precision-matched springs

When pushing your engine to its limits, the valvetrain is the first place to show weakness. These springs are manufactured using advanced heat-treatment processes to ensure they maintain their tension under extreme thermal conditions. By reducing the mass of the retainer and spring assembly, you gain improved valvetrain stability, which is essential for preventing valve float during high-speed operation. Whether you are upgrading your daily driver or a dedicated weekend racer, these springs offer the perfect balance of strength and weight reduction. Trust the experts at GGCRACING for your next engine build.
