Description
Performance Handling Upgrade. If you are installing a new set of lowering springs on your Pony it is a good time to replace your old worn out stock factory rubber Spring Isolators with a new polyurethane set from Prothane for improved handling and a better overall driving performance. Polyurethane Construction. Prothane isolators are made from a polyurethane material which is far superior than standard rubber. Polyurethane is unique in that it has the elasticity properties of rubber combined with the durability of metal, making it ideal for suspension bushings.

Application. This set of upper and lower Prothane Rear Spring Isolators are designed for use on 1979 to 2004 Mustangs, including the LX 5.0, V6, GT, Bullitt, Mach 1, and 1993-1998 SVT Cobra models. Does

not fit 1999-2004 IRS-equipped SVT Cobras.

    100x's better than the factory rubber

    April 19, 2013

    These prothane isolators are a must for anyone replacing or upgarding springs. I bought the SR lowering springs and new shocks and struts along with these and they are a perfect match. I removed the factory springs (spring compresser recomended) and had it all installed in the better half of the afternoon. The old rubber isolators were completley shot. The prothane looks like its going to last a loooong time and they fit perfect in the factory location. I called my alignment shop and was out driving that evening. I love the new stance of my Cobra, and no more squeeky factory isolators BUY these if your changing springs!!!!

    Must have

    October 03, 2013

    A must have when changing out springs on your mustang. Do not reuse the factory ones no matter how good of condition they are in.

    March 01, 2014

    I ordered these with some a ford racing lowering B springs. The handling and stance improvement was very noticeable. These are definitely a good replacement part for worn out factory isolators

    Great Product

    January 24, 2014

    These isolators are a great product, not going to say they are what made the difference In the ride quality because that was probably the Springs/Struts/Shocks but they did quieten the ride down. No more popping, and metal to metal scrubbing noises.

    Keep the spring from being metal to metal

    November 29, 2013

    After 20 years the rubber is worn out and these poly isolators will last the life of the car. Great product at a great price.

    well worth the money

    November 23, 2013

    recently changed every single suspension component on my 03 gt and wanted these to go along with the build. while everything was apart it was extremely easy to install. word of advice, just spray these pieces with silicone spray to make it easy as pie installing and it'll prevent any chance of noise coming from them. once again AM I am overly pleased with your products, thank you guys.
