So when doing maintenance on my car I noticed that these insulators/isolators crumbled and broke off of the springs. I was wondering if you guys ever found a replacement. I look at oem parts site but they only show the springs, thats it. Let me know.
Pulled my deteriorated insulators out couple days ago... Called a couple Acura dealers and they knew nothing about these parts - hard to believe they are not serviced.

They are discontinued afaik. But you can get them for other acura models, not sure if that that would work tho lol. I've wondered how they are installed. 3m tape?
To be clear, I am talking about the sleeves that fit around the upper 2 coils of the rear springs. Not aware of any other model that has progressive rate rear springs for which these parts are used.
Maybe you have to buy the whole spring? I have ran into the oem parts for this on a bulb for our cars. The cover isn't shown in the Acura system and the bulb I received was clear instead of amber. On my civic there was a nifty little support that helped support the front bumper on the fender. Honda system doesn't show it either as existing. Normally we get to see the disappointing discontinued on parts.
The coil sleeves (2) per spring are covering the upper 2 coils on each spring. The springs are progressive rate - 190 lb/in for ride initially, then increase to 250 lb/in in corners as spring compresses further, to provide the awesome cornering balance ITR Is known for.
The sleeves do 2 things - first is to prevent the upper 2 coils from contacting each other, which would wear off the paint, cause corrosion and lead to spring failure. The 2nd is to make the transition point to the higher rate happen at a specific compression distance. Without the sleeves, cornering balance is not what it is supposed to be because the effective spring rate is lower than intended over most/all of the outside wheel travel
Interesting, I use these but yes you need to order 3 sets because each package comes with 2 so the 3rd set will cover what part of the coil you didn't cover. See images.
ITR Coil spring insulator/isolators?
