    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.

    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.

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

    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.

      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.

      Mach 1 suspension upgrade.

      My 2004 Mustang Mach 1 had a prior owner installed coil spring lowering kit that just wasn't correct. I replaced entire system with an Eibach pro kit, Koni shocks and used these spring isolators to compliment the new system. My mechanic had no problems with these and they installed easily. My cars handling is night and day better! I highly recommend these, they are priced fairly and worked out perfectly.

      Awesome

      I had springs put in a few years ago without isolators. I didn’t like how it rode. Put these in with the rears. Wow what a world of difference. If ur putting in springs make sure to use new isolators.

      Good Product

      Quality isolaters, good fitment and high quality. Took about 2 hours to install. If you’re going to lower your car with new springs, do your self a favor and grab these too.

      Worked as expected

      These worked as expected. To put the lower isolator make sure to put a bit of lube inside to make it easier to install. My voglund springs did come with upper isolators, so if you only need uppers you can skip these

      Poly Iso's

      Quality product from SR performance, no complaints at all. Use a large mallet to put the bottom isolator on and you'll be all set. They're no thicker than the stock iso's but the polyurethane material makes them less susceptible to deflection. With the age of these cars it's a no brainer to upgrade to these iso's while changing springs.

      this is a quality part and good bang for the buck.the lower isolator is hard to get on without grinding a little off inside end of spring.

      A definite must have!

      After upgrading the stock suspension to Eibach pro, I was relatively disappointed in the ride quality. After reading the claims of the increased ride quality, I decided to give them a shot and man, the improvement was amazing...definitely replace the old worn out factory iso with these and you won’t be disappointed! The install was super easy and took a total of 3 hours.
