Cam Phaser Limiter Kit for GM LT4

The COMP Cams Cam Phaser Limiter Kit (Part Number 5450) is engineered for GM LT4 engines to facilitate the installation of more aggressive camshaft profiles. This kit functions by restricting the cam phaser's motion, which is crucial when upgrading to high-performance camshafts that might otherwise interfere with the stock phaser mechanism. Included in the kit is a specialized tool designed for the simultaneous compression of phaser springs in 2015 and newer GM LT4 engines. This ensures that the spring lock engages correctly at its optimal position. By installing the provided limiter plug, the necessary valve clearance is achieved for these high-performance camshafts, while still preserving the functional benefits of the Variable Valve Timing (VVT) technology. This modification, when paired with more aggressive camshafts, has been shown to yield substantial gains in upper-RPM performance without compromising the engine's low-end or mid-range power delivery. The kit is specifically noted for its application in Gen V LT4 engines, ensuring precise compatibility and function for enthusiasts looking to push their engine's performance envelope.
