Features & Details

  • Required for Installation of Comp Cams
  • Eliminate Piston to Valve Clearance Issues
  • Limits Cam Phasing to 20 Crank Degrees
  • Fits 2005-2007 Modular 3V 4.6L Engine
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 2007 3 valve 4.6L powered Mustangs running aftermarket Comp Cams.

Does this part turn your engine into a non interference engine?

  • Hello! The Comp Cams Phaser Limiter Kit does not turn your engine into a non interference engine.

    VincentV

I noticed the product says 05-07 GT. My car being a 2008 GT, would I not need these? Or is there something else i should be looking for? I'm planning on installing the Mother-Thumper Competition cams soon and I'm trying to make sure I have everything necessary. Would you be able to shed some light on this mystery for me?

  • These Comp Cams Phaser Limiter Kit fit 2005-Newer Ford 4.6L/5.4L Modular 3 Valves, so this would absolutely work with your 2008 GT. Comp Cams specifies that this phaser limiter kit only works with the factory phaser, and will not function properly with aftermarket phasers. Additionally, you would also need the Ford Performance 3V Cam Phaser Bolts for the installation of new camshafts, and we would also recommend using a engine break-in oil to properly break in the camshafts. Here is the link for the Phaser Bolts, as well as the break-in oil: http://www.americanmuscle.com/ford-racing-cam-phaser-bolts-0510gt.html http://www.americanmuscle.com/royalpurple-breakin-oil.html

  • The Comp Cams Phaser Limiter Kit will only come with (2) Phase Limiter Plates and the Cam Phaser Disassembly Tool.

Would this be necessary for a set of ford racing hot rod cams on a 3v? If not would it still be beneficial to have installed with the Ford racing cams?

  • The Comp Cams Phaser Limiter Kit (05-07 GT) are specifically designed for camshafts manufactured by Comp Cams, so because of this these will not work with Hot Rod cams by Ford Racing.

    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.

    Great product.

    Pretty much have to get the phaser limiters if you run the mother thumpr cams. But they were easy and quick to install.

    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.

    A must for comp cams

    Saved your self the headache of dealing with special pistons and worrying about clearance issues. This Phaser Limiter kit allows the stock ECU to control your variable valve timing with the proper tune.

    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)

    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.
