COMP Cams¨ Chrysler Hemi Phaser Camshafts utilize Variable Valve Timing (VVT) technology to maximize power and performance in stock and street/strip applications.

The new Hemi engines from Chrysler are great power plants straight from the factory, with technology that allows the camshaft to move in real time. Instead of scrapping this advanced system, COMP Cams¨ has embraced it with a new line of aftermarket Hemi specific cams. These patent pending Hemi Phaser Camshafts work with phaser limiters or locks to fully utilize Chrysler's Variable Valve Timing (VVT) technology, which allows the camshaft to pick up torque in the low end of the engine while maintaining power up high. Made from a billet core, these hydraulic roller cams are engineered tough enough to handle 5.7L and 6.4L Hemi street /strip engines. Their unique design maintains piston to valve clearance while enabling high performance lobes utilizing VVT, making them perfect for late model Dodge Challengers, Dodge Chargers, Chrysler 300s, Jeeps, Dodge trucks and Mopar crate engines with VVT. The camshafts are available as both custom and three different off-the-shelf grinds dependent upon engine type for improved performance over OEM options. COMP Cams¨ Phaser Limiter or Lock Kits limit the degree of maximum cam phasing to 14 crank degrees (7 cam degrees) and are required for use.

This Cam requires Additional Parts All Available Through HHP:


  • Comp Cams Phase Limiter
  • HHP Spring Kit 2 (Springs/Retainers/Locators)
  • Non-MDS Lifters For Automatic Transmissions
  • Custom Tuning

With our in-house test car, a 2009 5.7L VVT 6-Speed Challenger with stock engine, 1.75" Long Tube Headers, Cat-Back, CAI and cooler Thermostat, we tested this new camshaft for Comp Cams and we were extremely surprised by the results. Tuning the VVT HEMI with a big camshaft was a challenge but we are extremely happy with the results and the new lopey idle this car has. Take a look at the pics above or watch the video below to learn more about what this new camshaft and HHP can do for you.
