While Cam phasers provide tremendous efficiency benefits, they also present some limitations when it comes to performance Camshafts. In turn, COMP Cams has developed U.S. Patented Cam Phaser Limiter and Lock Kits for Chrysler HEMI 5.7L, 6.1L and 6.4L V8 engines. The limiter kits limit maximum Cam phasing to 14 crank degrees (7 Cam degrees) to provide the necessary piston to valve clearance when using larger aftermarket Camshafts. Meanwhile, lock kits take all movement out of the phaser. Combining these performance modifications with more aggressive Cam profiles will result in larger upper RPM gains without sacrificing any bottom end or mid-range performance. COMP Cams Phaser Limiter and Lock Kits are one-of-a-kind, as they are the first phaser tools designed specifically for HEMI engines.
This phaser limiter kit for ’08+ Chrysler 5.7-6.4L HEMI engines comes complete with the phaser limiter, limiter tool and instructions for proper installation. This kit limits the range of cam movement to 14 degrees. -
The Phaser Limiters and Adjustable Phaser Locks, which took home the honor of Best New Performance-Racing Product at the 2010 SEMA show, allow independent control over intake and exhaust centerlines, and eliminate piston to valve clearance issues that can occur when using larger aftermarket Camshafts in 2011 Ford 5.0L Modular V8 engines. The U.S. Patented COMP Cams Phaser Limiters for the 5.0L Coyote Modular V8 Engines physically limit maximum Cam phasing to 20 crank degrees (10 Cam degrees). Four separate phaser limiters, with the proper tuning software, allow the OEM computer to independently control intake and exhaust centerlines. Take full advantage of the benefits of Variable Valve Timing (VVT) when using aggressive aftermarket Camshafts without needing to install custom pistons to eliminate valve clearance issues. For maximum performance, custom remapping of the Cam phasing ECU control tables is required.Physically limit maximum Cam phasing to avoid piston to valve clearance issues with aggressive camsFour phaser limiters or locks offer precise, independent control over intake and exhaust centerlinesPhaser limiters physically limit Cam phasing to 20 crank degrees (10 Cam degrees) while allocating maximum intake advance and exhaust retardAllows use of larger, more aggressive aftermarket Camshafts in 2011 Ford 5.0L Modular V8 engines
This limiter kit for ’11-’14 Ford 5.0L Coyote limits the cam phasing to 25 crank degrees for camshafts with more duration and lift. By keeping VVT while adding larger camshafts, more power is gained without sacrificing bottom end torque. -

COMP Cams offers two types of kits to replace stock valve train components for more useable horsepower and a higher rpm operating range. The first is our RPM kit, which includes Pushrods, valve springs and retainers. The second RPM plus kit has the same components but also includes lifters allowing for a complete valve train buildup for a new cam.

COMP Cams HEMI pushrod sets are a continuation of the Hi-Tech Pushrod line. These pushrods sets are engineered to provide optimal preload for specific late-model HEMI applications when using performance camshafts. Like all COMP Cams Hi-Tech Pushrods, these are a one-piece construction from .080” wall chromemoly tubing and are cryo-treated for extended durability. In addition, they feature precision formed and reinforced ball type ends, and the whole pushrod is black oxide finished and laser etched. COMP Cams Hi-Tech Pushrod Sets are available for the 2003-08 5.7L, 2005-10 6.1L and 2009-Current 5.7L/6.4L HEMI applications.
Featuring 0.080″ wall thickness, precision formed and reinforced 5/16″ ball ends and heat-treated, this pushrod set offers a drop-in performance upgrade for ’09+ Dodge 5.7/6.4L HEMI engines with performance camshafts.
Available for ’03-’08 5.7L HEMI under 8720-16. Available for ’05-’10 6.1L HEMI under 8722-16.

The Pushrod is one of the most important pieces of the valve train, but all too often it’s taken for granted. pushrods not only have to be strong enough to not fail, bend or burn up at the ends, they must also match the frequency of all the rest of the pa parts in the valve train, as well as the rpm at which the engine will be run. Today’s all-out race engines demand the highest quality components at every step, and COMP Cams Hi-Tech pushrods fill that requirement. Hi-Techâ„¢ pushrods feature a one-piece design from .080″ wall, seamless chromemoly tubing that ensures the ultimate in strength and durability. Ends are precision formed, yielding added thickness and strength in the critical tip area, while maintaining constant wall thickness and concentricity. The pushrods are then heat-treated for maximum strength to ensure compatibility with guide plates. They are OD ground for consistency and black-oxide finished with length and part number laser etched on the OD for ease of identification.
