Fits 2006-2011 Ford Crown Victoria, Lincoln Town Car, and Mercury Grand Marquis with Ford Modular 3V engines.

Standard Ford Modular 3V cam phasers are computer-controlled cam gears that can retard timing by up to 60 crank degrees to optimize efficiency. While effective for fuel economy, this wide range of movement creates significant piston-to-valve clearance issues when installing performance camshafts. The U.S. Patented COMP Cams Cam Phaser Limiter Kit solves this by restricting the timing movement to just 20 degrees.

By limiting the phaser's range, you gain the necessary clearance to run aggressive cam profiles with tighter lobe separations, unlocking massive upper-RPM power gains without sacrificing bottom-end or mid-range performance. This kit allows you to maintain the functional benefits of Variable Valve Timing (VVT) while ensuring engine safety under high-performance conditions.
