Cam Phaser Lockout Kit GM 07-08 L92 & GEN V LT1

The Cam Phaser Lockout Kit GM 07-08 L92 & GEN V LT1 from COMP CAMS is a precision engine management solution designed for owners of fifth-generation Chevrolet LS and modern LT-series engines who demand maximum valvetrain stability and reliability. Variable valve timing systems, while effective for emissions control and fuel economy across broad RPM ranges, introduce unwanted complexity and potential failure points in high-performance applications. This lockout kit eliminates that variable phasing by mechanically locking the camshaft phaser in a fixed position, delivering the tuning consistency and repeatability that serious builders and enthusiasts demand.

The kit works by preventing the phaser's oil-driven actuator from shifting camshaft timing, which removes parasitic losses associated with phaser wear and eliminates timing drift under high-boost or nitrous conditions. By locking phaser travel, builders gain complete control over ignition and injection timing across all load states—a critical advantage when running standalone ECU tuning, custom fuel mapping, or extreme power adders. The design maintains full structural integrity of the cam drive while removing only the variable actuation mechanism, preserving engine reliability while unlocking repeatability for dyno work, drag racing, and street performance platforms.

Installation suits 2007–2008 LS-platform vehicles equipped with the L92 engine as well as fifth-generation LT1 engines in newer Chevrolet Corvette, Camaro, and CTS-V models. Mechanics and tuners frequently specify this lockout kit during full engine builds, forced-induction conversions, or when migrating to aftermarket engine management systems where OEM phaser logic no longer applies. The compact 0.59 lb design integrates cleanly without requiring structural modifications, making it ideal for both weekend enthusiasts performing engine work and professional shops supporting high-horsepower builds.
