Justin: If you're getting ready to install an aftermarket set of lowering springs on that '79 to '04 Mustang at home, well then grabbing a new set of isolators should be at the top of your list as those factory options are probably pretty beat after a couple of decades of wear and tear. Now, the SR options that we have here will be made from graphite infused urethane that will help provide you and your ride with years of quiet and trouble-free use all for right around 30 bucks for the front set. Now, your installation will involve removal of the front spring, so automatically the site's gonna kick this one up to a soft three out of three wrenches on the difficulty meter, take you about an hour or so to complete per side depending on how quickly you like to work. However, guys, if you hang out with me for a little bit, we'll show you more on the job later in the video.So, this is gonna be a short little PSA, if you will, about the importance of replacing your factory isolators if you haven't done so already. Now, as you may or may not know those factory isolators can get a bit brittle over the course of 20 to 30 years and can deteriorate leading to metal on metal contact which is basically gonna result in some unpleasant noises. Not only that, but if the factory isolator is completely wasted, it can even lead to some sloppiness in your ride quality as well, as some of our customers have pointed out in the customer review section. Now, this kit from SR performance is going to completely replace both the top and bottom isolators on the front of your '79 to '04 Mustang. Now ideally, if you are replacing these isolates at the same time as swapping a set of lowering springs then obviously would make a lot of sense to knock out the rears as well. And if you are gonna do that, well you can just so happen to find the SR Performance matching rear isolators here on the site for around 20 to 25 bucks. Now the isolator themselves will be made from a durable urethane material which is then infused or impregnated with the graphite here to help prevent these things from drying out and deteriorating on you like those stockers.And with that said guys, these are gonna be completely maintenance-free, right? You don't have to grease them or anything like that over the years. But now we wanna show you just what it takes to get these guys in place and to do so, here is your detailed walkthrough we promised you earlier along with a quick tool break down.Man: The tools used for this install are a half-inch impact gun, a 3/8 impact gun, a 3/8 ratchet, an 18-millimeter wrench, a 24-millimeter socket, a 15-millimeter socket, and a pry bar. So, the first step of this install is gonna be to get the front end of your vehicle up off the ground and pull the front wheels. This will give you the access to remove your caliper and your rotor. Once you do that, then you can start disassembling the rest of the front suspension to get your front spring out. Next, I'm gonna unhook the sway bar end link and then I'm gonna put some support underneath the lower control arm while I disconnect the shock.Now I put a floor jack underneath my lower control arm to support my spring while I disconnect my shock assembly here at the front. This is gonna keep the spring from unloading uncontrollably while you're unbolting the strut assembly from the knuckle. Now I'm gonna use a little bit of leverage to get underneath the coil spring, push down on the lower control arm and remove the spring. Now I can just grab on to my isolator here at the bottom and just unravel it from the coil spring. Now I'm just gonna apply a little bit of lubricant to help get my new isolator onto the bottom of my coil spring. Now that I've got my new isolators installed, I can reinstall my coil spring back into the pocket for the lower control arm. Now that I have the coil spring seated on one edge of the pocket, I can use a floor jack to slowly raise the lower control arm into place and seat the spring properly. Make sure when you raise your lower control arm back up that you line up the sway bar end link with the sway bar hole.Once I was able to use my floor jack to raise the lower control arm up to the proper height, I can reinstall my rubber bushing for my sway bar end link that I lined up while raising everything. And then I can put my bolts back in from the knuckle to the strut assembly. Now I can reconnect my ABS clips and route the wire harness as per factory. Now I can tighten up my sway bar end link bolt. Now you can reinstall your calipers, throw your wheels back on, and you're pretty much all wrapped up. And now you can repeat this process on the other side as it's exactly the same. And that's gonna wrap this review and install of the SR Performance Polyurethane Front Spring Isolators for your '99 to '04 Mustang.

Much better than the stock rubber isolators
These are a must when replacing the OEM rubber spring isolators, especially at high mileage. Replaced mine at 285k miles and the old ones were so badly seized onto the control arms, so much that they broke off a piece of the old springs. If you're doing any kind of front suspension work or even just lowering springs, get these - definitely worth it. Just be sure to put some Vaseline or lubricant on the springs to help with pushing the tubes on!Helpful (0)
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.
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.
Do I need spring isolators? Or can I instal with out them?
Aftermarket springs can be installed without spring isolators but may initially create a small creaking noise that will be caused by the metal-to-metal contact from the spring and struts.
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.
You would not need these for the top and bottom no.
