Product Description

The COMP Cams 5456 is a cam phaser limiter kit specifically designed for GM Gen IV and Gen V VVT engines. By limiting the variable valve timing to around 20° of crankshaft movement, it provides increased piston-to-valve clearance - making it safer to run more aggressive performance cams without risking interference.

This kit includes limiter plates, a spring compressor / lock tool for safe installation of the VVT spring, and a special tool for handling the cam phaser's trigger wheel. It's ideal for high-performance builds that still want to retain a portion of the VVT functionality, giving you both better clearance and more consistent high-RPM behavior.
