These Performer RPM Chrysler Magnum heads give substantial performance improvements for street/strip and off-road performance use. They offer an easy bolt-on engine upgrade with substantial out-of-the-box performance gains. Stock Magnum intake and exhaust flange and port locations make these heads an ideal choice for use with stock equipment as well as the new RPM Air-Gap manifold. These heads feature a slight increase in compression over the factory heads, offer more flow than stock, and accept adjustable aftermarket rocker arms. These heads are available in bare or assembled versions; hardened pushrods are required.

COMP Cams HRT Stage 1 camshafts use the newest and most advanced lobe designs in order to produce some of the highest average power and torque available. The "Low Shock Technology" features lobe profiles designed to maximize horsepower while improving stability at higher engine speeds. These profiles are also easier on the valve springs, enhancing durability and reducing load loss. COMP Cams HRT camshafts receive the Micro Surface Enhancement (MSE) finishing process as a standard feature, which increases strength and performance by reducing surface peak roughness and provides a 250 percent improvement in the effective load bearing area, allowing for much higher loads. All HRT Stage 1 camshafts do not require upgraded valve springs.

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 camshafts 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. The patent-pending Hemi phaser camshafts work with phaser limiters or locks to fully utilize Chrysler's Variable Valve Timing (VVT) technology, which allows them 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, no-springs-required 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. COMP Cams Chrysler Hemi phaser camshafts are available as both custom and three different off-the-shelf grinds, dependent upon engine type, for improved performance over OEM options. They will require the COMP Cams phaser limiter or lock kits to limit the degree of maximum cam phasing to 14 crank degrees (7 cam degrees) and they are available separately.
