COMP Cams Cam Phaser Kit Ford 3V Limiter

If you're looking to get more out of your 2006-2011 Ford Crown Victoria's 4.6L 3-valve engine, especially when installing performance camshafts, this Cam Phaser Limiter Kit from COMP Cams is a smart move. The factory variable valve timing (VVT) system is great for optimizing efficiency across the RPM range, but it also limits piston-to-valve clearance. This restriction means you can't run many of the more aggressive camshaft profiles that offer significant upper-RPM power gains. This kit addresses that limitation directly.

COMP Cams' patented design restricts the cam timing movement to 20 degrees, which is enough to still benefit from VVT technology while creating the necessary clearance for tighter lobe separation performance cams. This modification, when paired with a more aggressive cam, has shown some of the biggest upper-RPM gains seen from simple valvetrain changes, without hurting your low-end or mid-range power. The kit includes the phaser limiters, a spring compressor, a spring lock tool, and instructions to help you get it installed.
