        I have SR Coilovers... I don't need these right?

        • The SR Performance Polyurethane Spring Isolators are for use if and when you replace your springs or decide to upgrade to lowering springs. If you purchased the SR Performance Coilovers, you will not need these with that install.

        Helpful (1)

        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.

        So these are just for the rear? Would this cover all i need if I decoder to go for sr lowering springs?

        • These are for the front only. Other components are needed when installing lowering springs, feel free to give us a call to discuss details.

        Helpful (0)

        Does the front shocks need isolators for the top and bottom of the spring?

        • You would not need these for the top and bottom no.

        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?

        • 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

            I think anyone who runs a pony to buy this set of springs. Handles fantastic, and looks great. Easy to install. It took a friend and myself two hours to install in my driveway.

            Although a must to replace when you change springs the one rubber hose isolator was very difficult to install so we left it out...very tight fitment

            Almost perfect

            Fit fine with stock control arms. Had to shave a little bit off one of the isolators when I upgraded to tubular control arms. No issues though.

            You need this.

            I was worried these would be to thick, but no there perfect. With HandR SS springs the car will be about 2inches lower. Not a slammed look but not a 4x4 anymore. For me its perfect.
