COMP Cams Phaser

COMP Cams phaser limiters and lockout kits are made for late-model GM and Chrysler HEMI engines that use variable valve timing (VVT). They are also called cam phaser lockout kits, cam phaser limiter kits, or phaser lock kits. They are designed for engine builders who install a performance camshaft and want to remove or restrict the factory phaser system.

Key Features:

• Limits or locks out the factory cam phaser to give more predictable, fixed cam timing
• Made for use with aftermarket camshaft upgrades in supported GM and Chrysler engines
• Helps simplify valvetrain operation when a custom cam profile is installed
• Built by COMP Cams, a well-known name in camshafts and valvetrain components

These parts are engineered with the performance builder in mind. They help turn a variable-timing engine into a fixed-timing setup that works well with a performance cam. Each part number in this line covers a specific engine family, so choose the variant that matches your application. Many installations also need a custom engine tune.
