Product Details

The COMP Cams CK54-307-11 is a Stage 2 LST (Low Shock Technology) Camshaft Kit engineered for manual-transmission LS3 engines running aftermarket pistons with valve reliefs. Designed to extract maximum horsepower from drag race and street/strip LS3 builds, this kit takes the guesswork out of selecting and matching the right valvetrain components for your application.

COMP Cams' Low Shock Technology (LST) lobe profiles are precision-engineered to maximize horsepower output while improving valvetrain stability at high RPM. The aggressive lobe designs are also gentler on valve springs, enhancing durability and reducing spring load loss over time. Every component in this CK-Kit has been Spintron and dyno-tested together to ensure a perfectly matched, high-performance valvetrain package.
