Advanced Beehive Design for GM LS

The PAC Racing Springs 1200 Series Ovate Beehive Valve Spring is the gold standard for GM LS-Series engine upgrades. The unique beehive shape reduces the mass of the valve spring retainer, allowing for higher RPM potential and improved valvetrain stability. By utilizing an ovate wire profile, these springs offer a more efficient stress distribution compared to standard round-wire springs, resulting in increased fatigue life and better performance under load.

Technical Specifications

  • Series: 1200 Ovate Beehive
  • Outer Diameter: 0.885 / 1.307 inches
  • Spring Rate: 340 lb/in
  • Coil Bind: 1.100 inches
  • Compatibility: GM LS-Series Engines

Designed specifically for the LS platform, these springs are the ideal choice for street and strip applications. The reduced mass of the beehive design allows the valvetrain to follow the camshaft profile more accurately, reducing the risk of valve float at high engine speeds. This translates into improved power delivery and enhanced engine responsiveness. Whether you are installing an aftermarket camshaft or simply refreshing your valvetrain, these springs provide the durability and performance you need. Each spring is precision-wound to ensure consistent pressure and long-term reliability. Upgrade your LS engine with the trusted performance of PAC Racing and experience improved valvetrain efficiency.
