Perfect fit

I had no priblems installing these on my Ford 'C' coil springs. Fit like a glove. Would recommend installing these when switching out your factory coil springs.

Do you have to apply any grease to the isolators? I know poly suspension bushings usually require greasing to keep the noise down - are these similar? or just plug-n-play without any greasing needed?

  • No grease is required or recommended. Very clean install and no squeaks when I installed them with new lowering springs.

How much does it raise the front?? I bought some H&R lowering springs for my 04 cobra convertible and whoever had her before me lowered it without isolators and i didn't buy new ones. it sits too low really and bottoms out way too much. how much can i expect these isolators to raise the car back up? besides a different set of springs what can i do to raise her up a little if the isolators aren't enough?

Bare

  • You can expect these Isolators to increase the ride height of your car no more than 1/4" to 3/8". Figure the thickness of the Isolators (top and botton) minus a small amount for comression of the Polyurethane.

    Great Product

    These things are awesome when i replaced my springs with bbk super sport lowering springs and had seen how nasty the stock isolators were i knew it was a good thing that i had purchased these i would recommend getting some silicone spray it helped to get the bottom isolator on the spring but the drastically improved the feel of the spring in my 04 Mustang GT

    a MUST if lowering your car

    i thought my car would have good stock isolators to reuse when i got my springs, but soon i found out that they are worn out! these things are a must if you are lowering your mustang and want to avoid squeaky noises that are going to make your car sound like a hoopty. do not regret buying these (not to mention the material feels extremely sturdy)

    Needed part

    If you plan on either upgrading or lowering your Stang, you will need to get these. They are very easy to install and will help if your stock ones are bad or if you just want to replace the ones you have now.

    Front spring Isloators

    The upper front spring isolators went in with no problem, the lower isolators were to thick to install, my front end guy left them out. My LX drives and handles great without them. Time will tell after driving it for a while will see how it works. I would recommend this kit if you are rebuilding your suspension.

    Great isolators, great price

    Absolutely great isolators, great quality and easy to install. Come at a great price and you can avoid having to wrap your springs in electrical tape for a much cleaner install. Highly recommended if you are replacing your springs!

    waste of money

    the lower isolator was impossible to get into the coil of the spring. Ended up having to use the stock isolators.

    I didn't listen to AM recommendation when purchasing lowering springs. Man oh man were my factory isolators DONE. Completely shredded and hanging on with cracks. I'm glad I'm at peace with these.
