Product Details

COMP Cams Engine Valve Springs are a cornerstone of high-performance valvetrain engineering, trusted by professional engine builders and performance enthusiasts across street, strip, and all-out race applications. As one of the most critical components in any engine, valve springs must be precisely matched to the camshaft and valvetrain system to unlock full engine potential — and COMP Cams delivers that precision across their entire spring lineup.

COMP Cams offers valve springs in a wide range of configurations to suit virtually every build level and application. Their lineup includes traditional single, dual, and triple coil designs as well as advanced beehive and conical spring profiles — each engineered to address specific valvetrain demands across varying RPM ranges and valve lift levels.

Key Features & Benefits:

  • Multiple spring configurations — single, dual, triple, beehive, and conical designs available to match a wide range of camshaft and valvetrain setups
  • Conical and beehive profiles reduce active coil mass, lowering dynamic valvetrain forces and extending the service life of all valvetrain components
  • Progressive natural frequency design dampens coil oscillations and improves dynamic stability, raising the RPM ceiling while reducing harmful resonance
  • Precision load matching — each set is matched for load consistency to deliver reliable seat pressure and open pressure across every cylinder
  • Rust-preventative factory coating protects springs throughout the assembly and break-in process
  • Broad application coverage — options spanning mild street performance builds through extreme high-RPM race engines, including GM LS/LT, Ford Coyote, Dodge HEMI, Duramax diesel, and more
  • Engineered to complement COMP Cams camshafts and valvetrain components for a fully optimized, correctly loaded valvetrain system

Proper valve spring selection is one of the most critical — and most commonly overlooked — aspects of a performance engine build. An incorrectly specified spring remains one of the leading causes of premature valvetrain failure. COMP Cams takes the guesswork out of the process by offering a comprehensive, well-documented spring lineup engineered to deliver correct seat pressure and open pressure at every lift point. Whether you're building a reliable weekend street cruiser or a full-race powerplant, COMP Cams Engine Valve Springs provide the precision, durability, and performance your build demands.
