Comp Cams Phaser Lock for Hemi 5.7/6.1/6.4

This is the COMP Cams Phaser Lock, part number 5760-L, designed for Hemi engines. Specifically, it's made for the 5.7L, 6.1L, and 6.4L displacements. This part is crucial for anyone looking to lock the variable valve timing (VVT) phaser on these popular Mopar engines. By locking the phaser, you ensure a fixed camshaft timing position, which is often necessary when installing a performance camshaft that isn't designed to work with the factory VVT system.

When you upgrade your Hemi's camshaft, the factory VVT system can sometimes cause issues or prevent the new cam from reaching its full potential. The COMP Cams Phaser Lock is a well-built component that physically secures the phaser in a set position. This eliminates any potential for the VVT system to retard or advance the cam timing unexpectedly, allowing your new camshaft to perform as intended. It's a straightforward way to ensure your engine build is reliable and makes the power you expect from your performance modifications.

Installing this phaser lock is a common step when rebuilding or modifying the top end of a Hemi engine. Make sure to consult your camshaft manufacturer's installation instructions, as they will typically specify if a phaser lock is required and provide guidance on its use.
