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.

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?

Nate

  • The reason why this is will not work for your 2008 GT is because there is a special tool needed for the 2008-2010 Mustangs that this kit does not include. Unfortunately, we do not sell this tool.

Question Resolved

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?

Silver06gt

  • 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.

    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)

    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.

    You need these for a big cam with stock heads. Again, you need these for a big cam.

    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.
