Product Details

The COMP Cams 7228TSD-KIT is a conical valve spring kit engineered specifically for the GM Gen V LT4 engine platform. Designed to support aggressive camshaft profiles, this kit accommodates up to .625" maximum valve lift and includes premium tool steel retainers for enhanced durability and reliability under high-performance conditions.

Conical valve springs offer a significant advantage over traditional dual or beehive spring designs by providing a progressively increasing spring rate as the valve opens. This helps eliminate harmonic resonance and spring surge at high RPM, keeping the valvetrain stable across a wide range of engine speeds. COMP Cams engineered this kit as a direct upgrade solution for LT4 applications running performance camshafts that demand more than the factory valvetrain can provide.

Key Features:

  • Conical spring design for improved harmonics and surge resistance at high RPM
  • .625" maximum lift capacity to support aggressive aftermarket camshaft profiles
  • Tool steel retainers for superior strength over standard stamped steel or aluminum units
  • Engineered specifically for the GM Gen V LT4 engine platform
  • Drop-in fitment compatible with factory LT4 cylinder heads
  • COMP Cams precision manufacturing for consistent seat and open pressures

Whether you're building a street/strip LT4 or a dedicated track car, the COMP Cams 7228TSD-KIT delivers the valvetrain integrity needed to match your camshaft upgrade and protect your engine investment at elevated RPM.
