Description
Performance Upgrade. If you are installing a new set of lowering springs it is a good time to replace your old worn out rubber Spring Isolators with a new set of SR Performance Polyurethane Spring Isolators available from AmericanMuscle.

Superior Materials. These SR Performance Polyurethane Spring Isolators are made from polyurethane that has been impregnated with graphite so they will not dry out and crack like the stock factory rubber pieces.

Application. Designed to replace the stock Rear rubber units found on the 1979-2004 Mustangs these SR Performance Spring Isolators will greatly improve the handling of your lowered pony. Not for use on SVT Cobra's with Independent Rear Suspension (IRS).

A MUST!!!!!

My old factory ones were torn pretty bad and this definately improved my ride. Great fit and pretty easy. IF you have a lowered car, you got to get some of these.

A must have

Don't install a set of springs without these isolators. They fit great and are tough. Much better than the stock rubber stuff.

    Needed part

    Jusat as the front isolators, these are needed if your old ones are going bad, if you lower your car, or just want to upgrade or replace.

    Great Isolators

    These are great Isolators, so much better than the hard, stock, plastic isolators. This is a must if you are going to change your springs.

    Poly isolators

    I run these front and back on my stang. They really help reduce road noise and squeaks from bare metal to metal contact. 15 min. install super easy!

    Rear Spring Isolator

    Great item! The factory ones that are made of rubber will crack, deteriorate, and fall apart. These new isolators are made of Polyurethane will last a lifetime. This will also help the rubbing that your springs against the body. No more creaking and cracking noises.

    Bad isolators out, good isolators in!

    As I replaced my rear axle I also added new control arms and shocks, I found the old rubber isolators to be in poor condition, as I suspected they would be. Replacing those with the new polyurethane pieces not only gives me better support for the springs, but they'll last longer as well. No problem to get to, just drop the lower control arms, pull out the springs, then buckle it all up. Anytime you can replace the rubber items with polyurethane replacements, do it! When I couldn't find these at the local parts store, AM had them!
