Ultimate Control for Drag Racing Valvetrains

When every millisecond counts, your valvetrain cannot afford to fail. The PAC Racing Springs 1200 Series 1.550 OD Dual Valve Spring is specifically engineered for the rigors of drag racing. This dual-spring configuration offers superior stability and load capacity, allowing for more aggressive camshaft profiles and higher lift without compromising the integrity of your engine.

Key Features and Performance Specs

  • Series: 1200 Series Drag Race
  • Design: Dual Spring configuration for maximum stability
  • Spring Rate: 644 lb/in
  • Coil Bind: 1.150 in
  • Outside Diameter: 1.550 in

The dual-spring design provides a redundant safety measure and superior harmonic control compared to single-spring setups. This is essential for high-RPM drag engines that experience rapid acceleration and intense thermal cycles. With a 644 lb/in spring rate, this component ensures your valves remain seated under extreme pressure, preventing float and power loss. PAC Racing is renowned for their metallurgical excellence, and this 1.550 OD spring is no exception, offering the durability needed to withstand repeated passes down the quarter-mile. Optimize your engine's potential and ensure long-term reliability with high-performance parts sourced from GGCRACING.
