Optimized Valvetrain Performance

The PAC Racing RPM Series 1.083 Ovate Beehive Valve Springs are engineered to optimize your engine's valvetrain for high-performance use. The unique beehive shape offers a significant reduction in moving mass, which is essential for achieving higher RPMs without sacrificing stability. The ovate wire design ensures that the spring can handle higher loads while maintaining excellent fatigue resistance, making these a reliable choice for any high-performance build.

Technical Specifications

  • Series: RPM Series
  • Design: Ovate Beehive
  • Outer Diameter: 0.720 / 1.083 inches
  • Spring Rate: 291 lb/in
  • Coil Bind: 0.952 inches
  • Quantity: Set of 16

These springs are designed to minimize harmonic resonance, which is a common cause of valve spring failure in high-RPM engines. By reducing the weight of the retainer and the spring itself, the valvetrain can react faster to the camshaft profile, resulting in improved power delivery and engine longevity. Whether you are building a dedicated track car or a high-output street machine, these beehive springs provide the perfect balance of strength and weight. Trust in the quality of PAC Racing to provide the components that keep your engine running at its peak. For all your high-performance automotive needs, rely on the experts at GGCRACING.
