Superior Valvetrain Control for LS Engines

The PAC Racing Springs 1200 Series Ovate Beehive Valve Spring is the premier choice for GM LS-Series performance enthusiasts. Utilizing an advanced ovate wire cross-section, these springs offer a significant performance advantage over traditional round-wire designs. The beehive shape effectively reduces valvetrain mass, which allows for higher RPM limits and faster valve response, ensuring your engine performs at its absolute best.

Technical Specifications

  • Series: 1200 Ovate Beehive
  • Outer Diameter: 0.885 / 1.290 inches
  • Spring Rate: 313 lb/in
  • Coil Bind: 1.140 inches
  • Compatibility: GM LS-Series Engines

These springs are engineered to handle the demands of both street performance and track-day use. By reducing the weight of the moving parts in the valvetrain, the beehive design minimizes the energy required to open and close the valves, leading to improved efficiency and reduced wear on camshaft lobes and lifters. The 1.290-inch outer diameter is specifically designed to fit standard LS cylinder head pockets, making this an excellent drop-in upgrade for many popular LS builds. Whether you are performing a camshaft swap or a full valvetrain rebuild, these springs provide the reliability and performance necessary for a high-revving engine. Trust in the quality of PAC Racing to keep your engine running smoothly and powerfully. Explore our extensive selection of performance engine parts and find the perfect fit for your vehicle at GGCRACING.
