      • Limits Cam Phasing to 20 Crank Degrees

      Description

      Limits Cam Phasing. COMP Cams Phaser Limiters physically limit maximum cam phasing to 20 degrees to allow independent control over intake and exhaust centerlines and eliminate piston to valve clearance issues that can occur when installing larger aftermarket camshafts in the modular 4.6L engine.

      Eliminates Need For Custom Pistons. This set phaser limiters, with the proper tuning software, allow the OEM computer to independently control intake and exhaust centerlines to take full advantage of the benefits of Variable Valve Timing (VVT) when using aggressive aftermarket camshafts without the need to install custom pistons to eliminate valve clearance issues.

      Application. The Comp Cams Phaser Limiter Kit is specifically designed for use on 2005 to 2010 3 valve 4.6L powered Mustangs running aftermarket Comp Cams.

      Please Note. The included Cam Phaser Disassembly Tool is not compatible on 2008-2010 models.

        Great until you realize...

        Everything fit perfectly until you realize you’re missing the phaser bolts. @Americanmuscle please don’t say it’s a kit if you’re not going to include all the parts needed and let people know before they have to wait 3 extra days for the right parts to come in. Thanks.

        5 2009 GT - David Installation Time: Less than 1 Hour

        09 improvise required

        My 09 GT/CS phaser spring did not match the instructions. The spring in the instructions should a spring that wrapped 180 deg around the pin. My phaser only made a 90 deg bend and the supplied tool would not work. I ended up clamping on to the spring end with vise grips, removing the pin bolt and manually unwrapping the spring. Installed the limiters and re-wrapped the spring and installed the pin. Be sure to not let the spring fling open, could damage the spring and hurt you too.

      Will this add horespower using stock cams? Or is this only needed when installing comp cams?

      • The Comp Cams Phaser Limiter Kit does not add horsepower, as its sole purpose is to eliminate piston-to-clearance issues with Comp Cams camshafts.

      Helpful (1)

      If I understand this correctly, these physically limit the number of degrees that the cam phasing can be altered by the VCT system. If the PCM commands a higher phase change than these will allow, won't a fault code be generated?

      Hello I went to put the limiters in and no matter what position I turn it the bolt holes never line up and it wont fit in the phaser in any position do I have to remove something else?

      • Please, double check to see that the cam position sensor has been removed. If the sensor is not removed, the Cam Phaser Spring Lock Tool will hit it when the engine is turned over.

      Will these limiters work on OE phasers, or should I be looking to replace them with something compatible?

      • The Comp Cams Phaser Limiter Kit is compatible with the OEM cam phasers.

      Will I not need a disassembly tool for my 2009 gt? And can the car be "tuned" through bama or would I have to go and get it "computer" dunk tuned!

      • The Comp Cams Phaser Limiter Kit does not come with a specific tool to install them on a 2009 GT. We suggest having a professional shop install these parts. Bama will be able to tune for this Limiter Kit.
