Product Details

The COMP Cams 26918TSD-KIT is a complete beehive valve spring kit engineered specifically for the GM Gen V LT4 engine platform. Designed to support aggressive camshaft profiles with up to .600" maximum lift, this kit delivers the valvetrain stability and control needed for high-performance street and track applications.

COMP Cams' beehive spring design reduces reciprocating mass at the top of the spring, allowing for improved rpm capability and reduced spring surge compared to traditional cylindrical springs. The tapered profile also allows the use of smaller, lighter retainers, further reducing valvetrain weight for better throttle response and high-rpm stability.

This kit includes tool steel retainers, which offer superior strength and wear resistance over stamped steel units — making them an ideal choice for forced-induction or high-output LT4 builds where reliability under extreme conditions is essential.

Key Features:

  • Beehive spring design reduces valvetrain mass and minimizes spring surge
  • Supports up to .600" maximum valve lift
  • Designed specifically for the GM Gen V LT4 engine
  • Includes tool steel retainers for enhanced durability and strength
  • Improved high-rpm valvetrain stability over OEM springs
  • Complete kit includes springs and retainers for a full engine build
  • Manufactured by COMP Cams to exacting tolerances for consistent performance

Whether you're upgrading a supercharged LT4 for increased power output or building a dedicated performance engine, the COMP Cams 26918TSD-KIT provides a reliable, high-quality valvetrain foundation engineered to meet the demands of modern LS/LT performance builds.
