High-Performance Valvetrain Stability

Experience superior engine reliability with the Howards Cams 1.470 Dual Valve Spring Kit. Engineered for high-RPM stability and durability, this kit is the perfect solution for performance-built engines requiring precise valve control. By utilizing a dual-spring design with an integrated damper, these springs effectively manage harmonic resonance, preventing valve float and ensuring consistent performance under aggressive cam profiles.

Technical Specifications

  • Spring Rate: 399 lb/in
  • Outer Diameter: 1.470 inches
  • Coil Bind Height: 1.080 inches
  • Material: High-strength alloy steel
  • Includes: Chromoly retainers and hardened locks

Whether you are building a street-strip machine or a dedicated track car, these springs offer the seat pressure and over-the-nose force necessary to maintain valvetrain integrity. The included chromoly retainers provide lightweight strength, reducing reciprocating mass and allowing for faster engine response. The dual-coil configuration provides a safety net; if an outer spring fails, the inner spring is designed to keep the valve from dropping into the cylinder, potentially saving your engine from catastrophic failure. Trust the engineering excellence of Howards Cams to keep your valvetrain operating at peak efficiency. Find all your high-performance engine components at GGCRACING.
