Product Details

The COMP Cams CK54-305-11 is a Stage 1 Low Shock Technology (LST) hydraulic roller camshaft kit engineered specifically for manual transmission LS3 applications running aftermarket pistons with valve reliefs. Designed for serious street and track builds, this kit delivers the best average horsepower across a wide RPM range, with valvetrain stability maintained all the way to 7,500 RPM.

COMP Cams' Low Shock Technology features lobe profiles engineered to maximize horsepower output while simultaneously improving valvetrain stability at elevated RPM. These profiles are also easier on valve springs, enhancing component durability and reducing spring load loss over time.

  • Cam Type: Hydraulic Roller
  • Grind Number: 298LMH11

  • Exhaust Duration @ .050" Lift: 254°
  • Advertised Intake Duration: 298°
  • Advertised Exhaust Duration: 303°

Kit Includes:

  • LST Hydraulic Roller Camshaft
  • Pushrods
  • Valve Springs
  • Retainers
  • Valve Locks
  • Spring Seats
  • Valve Seals

Important Notes:

  • Requires aftermarket pistons with valve reliefs — not compatible with factory LS3 pistons

  • Valve springs required and included in this CK kit
  • Recommended cam install kit: COMP Cams #5621

  • Recommended Max-Lift BSR Shaft Rocker System: COMP Cams #1982-16

This kit is ideal for LS3-powered builds targeting strong street/strip performance with a broad, usable powerband. The CK (Complete Kit) configuration removes the guesswork from valvetrain component matching, ensuring all included parts work in concert with the camshaft profile.
