I have everything I need to build another strut assembly using my lowering springs but am unclear on the need for the rubber sleeve at the bottom of the springs. The previous owner installed new strut assemblies that do not have anything at the bottom of the springs, they are seated in the strut, metal to metal. The parts diagrams list a sleeve for later GT500 models but not 2008. I called Steeda and spoke with someone who sounded unsure, he said I could transfer my sleeves over to the new assemblies, problems are 1) I'm not disassembling my old strut assemblies and 2) even if I were assembling them they do not have any sleeve isolators. Does anyone know if this is needed or should I just seat the new springs in the struts and move on? Thanks. Mike
Front coil spring isolator (sleeve) used on GT500?

My sleeves have rotted away and I need to pull everything down to change the strut mounts - again. Interested in whether there are replacements out there, or if they are even really needed.
I looked all over for these and couldn't find an exact replacement. I did find a comparable part at Autozone (sorry, I don't recall the part number). The fit was very tight for the bump stop, but they worked and didn't cost much. Might take the old boot/sleeve and bump stop in and compare at a parts store.

I've got the new boots and bump stops (actually the same ones Barspen linked.) What I need are the sleeves that go on the bottom coil where it sits in the strut assembly. I called my ford parts guy and he ordered 2 for me that will be in tomorrow. I couldn't locate them on any Ford diagrams on line so hopefully he got the correct ones. If they come in early enough tomorrow I'll go by and get them, if not I'll get them Friday and update if they are the correct parts and what the # is.
I have an 07 and never had any luck with new Ford OEM front spring isolators. I ordered 3 sets when I changed my springs and they were very brittle out of the bag, dry rotted I guess. What I did was measured the spring diameter with a set of calipers and measured a piece of the factory isolator to get the right thickness and purchased clear urethane tube and cut it to length.
Works perfect.

So do most people just run without them?
I use them. Also used them on my new eibachs. Figured that they are there for a good reason, and in didn't want metal to metal contact in the perch.
Others have run without them without issue as far as I know.

Some do out of frustration in not finding a replacement. I'd put them on. If you can't reuse your old ones, here's the Ford part no. 6R3Z-5L302-A. What I'm seeing shows it for 2011-2014, but I don't know why the earlier models would be different. I'm pretty sure they're sold each, so you'll need two.
6R3Z-5L302-A is the part # the Ford parts counter folks gave me for my 2008. Its a hard plastic type material that is split down the middle for easy install. I just got factory service manuals and they show the isolators on the spring picture but make no mention of it in the assembly / disassembly instructions.
I got 2 of the factory ford ones, went to install them yesterday and one split right down the middle, the other was ok so I used it. Must be old stock. What a pain, I'm going to try one more Ford one on Tuesday and if it doesn't work I'll be heading to Lowes and making my own!
Here is the cheapest I see on eBay (shipping included and no tax)........

I can imagine that at some point in the future the steel spring to steel seat will start to squeak without these spring insolators and that is probably why they are there to start with, what a pain to deal with if/when that happens!! OR you can just leave it alone and squeak like an old car.........
Are you also upgrading your strut mounts to the SVTPP/FRPP part number?

It's a bad design or one that is not meant to hold up long term. They glued the 2 halves together. I don't think its rubber, its too rigid. I ordered another today and have decided if it does the same thing I'll probably go with Fast Fords fix noted earlier in this thread. Just an FYI, I ordered from my local dealer who told me that they have 120 of them in their Greensboro facility. That means they probably have a lot of old stock, I am not getting my hopes up that the next one will be any better.
That's the same place the ones I ordered split or they just crumbled. I think the glue they use may have something to do with it in the sealed bag.
Mike, after cutting the tube to length I put them in boiling water for 30 seconds or so. Shoot me a PM if you need any help.

What material, specifically, did you use? You mention urethane, but what kind and where from? It would have to be pretty tough stuff to last any amount of time. Thanks.
The urethane tubing is the same thickness as the oem isolator material and the inside diameter of the tube matches the spring diameter. I picked the tube up at Lowe's. The durability of the tube is far superior to Fords plastic isolator due to the fact that it's flexible and not rigid.
