    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.

    I ordered this and it's not compatible with the own phasers I bought to replace my broken ones what phasers will work with these limiters

    GPLowe

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

    KenM

    • 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!

    MichaelJ

    • 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.

    I have an 05 Mustang GT and I am replacing my cam phasers with Dorman 917-250XD, are there any issues installing the Comp Cam Phaser Limiter Kit-5449 with these cam phasers.

    JohnrayC

    • That Dorman part number appears to be a direct replacement for the OE timing sprocket. Since that would be the same as the factory sprocket, there should be no issues installing the Comp Cams Phaser Limiter Kit on to your Mustang.

    What special tools would you use on a 2009 mustang, since the tools included doesn't work with 09-10.

    BryanB

    • Since the Comp Cams Phaser Limiter Kit does not come with a tool for the 2008-2010 Mustangs, some enthusiasts found that vice grips worked well. Though, we recommend being extremely careful as well as doing some more research for the proper way to install these Phasers.

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

    JohnnyD

    • 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.

      Phaser Kit

      Phaser are doing there job. I guess because engine hasn't blown up. Lol. I recommend that if your engine has more then 100000 miles to replace the actual phasers. The performance shop that did the work had issues with due to there age. They should be theroughly inspected once engine is opened. The Thumper cam requires the phaser Kit but not all cams required it.

      The install may have been hard to read due to a bad print but it was easy to follow and the specialty tools really made it easy to lockout the springs! Nice bolt on with any high lift Com Cams!

      Phaser review

      These are not exactly easy to install, if your phaser is old replace it first. I tried using a local part store phaser and it did not work the internal of the phaser is different. I had to purchase an original ford part.

      Phaser Limiter Kit 06 Mustang GT

      I am not a mechanic and the bulk of my experience is very basic. That said, the directions for installing these limiters are good enough to complete the job by anyone. The toughest thing for me was removing the cam gear without unwinding the spring. There are three tiny spot welds (so small you can barely see them) that holds the spring in place until the the timing chain is on the gear. MAKE SURE you use the tools in the cam installation for holding the phaser spring in place. $299 if one comes unwound,,,,ask me how I know. These things do what they say they will do. Also, make sure you use the timing chain tool to release the pressure from the tension bar on the timing chain. If you do not have the tool, do not attempt the install. It does what it is supposed to do so I give it five stars. I give American Muscle 10 stars.

      I installed these with the Comp Cam Motha Thumper cams, took about 20 minutes for these, just watch for the spring in the back of the sprocket.

      A must have product

      Bought the Comp Cam Phaser Limiter Kit for my 2005 Ford Mustang GT in order to install the Mothr Thumpr cams, also from Comp Cams. The Comp Cam Phasers are a must have product in order to install these cams, can't do it with out them. After the install, my car has been running great, wicked idle sound, but very smooth running. I highly recommend this product especially if it is required in order to do a cam install.

      Good Product tools may not work for your limiters

      Product fit well and wasn't too hard to install. The install tools however did not work on my phasers. I ended up using a pair of vise grips to unload the spring to install the limiters. (09 GT)
