COMP Cams#5761 Cam Phaser Limiter Kit for Chrysler 5.7L, 6.1L, 6.4L Hemi

Cam phasers are specially designed, computer-controlled cam gears that automatically optimize camshaft timing based on engine RPM. Engine oil is pressure fed to the phasers through passageways in the cylinder heads and cams. The engine's computer controls solenoids that adjust oil flow into and out of the phasers control chambers, giving the ability to retard the cams.

While this technology provides fuel efficiency and the ability to always be in the best position for maximum power regardless of engine RPM, it does present some limitations when it comes to performance cams. With such a wide range of valve timing movement, there is very little piston-to-valve clearance, which limits you to small cam profiles with little overlap.

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.

Comp Cams Cam Phaser Limiter Kits for 5.7L VVT and 6.4L VVT HEMI Engines restrict the range of cam timing movement, thus providing the necessary valve clearance for serious performance cams with tighter lobe separations while still utilizing the benefits of VVT technology. The resulting upper-RPM gains from using Comp Cams Cam Phaser Limiters are some of the largest from a camshaft swap without sacrificing any bottom end or mid-range performance.
