    Awesome part

    Huge upgrade over stock. It's nice that it came with the installation tool which is also a removal tool. Big difference compared to stock works perfect.

    A must have for the irs

    Recently ordered and installed this kit on my irs set up in my foxbody to replace the old worn out factory pieces. The install was incredibly easy to do and can be done on the car by following the directions supplied. It is doable by yourself but having a buddy over does make it slightly easier. And the end result is amazing. Highly recommend doing this.

    Great replacement from OEM

    I already had the IRS out of the car and noticed my joint boots were ripped and had signs of wear. With the tool this is a really easy install. Just use the press as instructed and they come right out. Don't confuse the dust cover ring for the actual axis joint retainer ring. You will also need a retaining ring pliers to get the new ones in. Tough to say the performance improvement of this specific item as I replaced all bushings at the same time.

    Great fitment

    First off the tool that comes with the joints make this job 1000x easier. The old joints pop out with no problem once the clips are removed and these slide right in. Couldn't ask for better fitment. No deflection and very solid quality pieces. Highly recommend!
