My car has lowering springs with no isolators. Im not sure if third gens came with isolators from the factory.

 

Both the front springs and the rear OEM springs sat in their pockers on isolators. The rear's commonly break down and rust away. Someone can correct me, but I think OEM style thirdeng isolators are no longer available, instead the 4th gen style (which I think is a bit thinker) is sold by dealers as a replacemnt. As for the fronts, I am not sure if they are any longer available.

The rears use isolators on top of the springs. The rubber part.

The fronts don't, they sit in the Kmember pocket, and around in the A-arm pocket. (unless I'm missing something).

 

The fronts have them as well, at the top of the spring. The fronts are alot thinner then the rears though.

 

you can buy front spring isolators from here: through Spohn PErf.

the rear's i duno; mine were fine, so i didnt ave to buy any; but ive heard that u can use 4th gen ones

 

According to Ed Miller, the fourthgen rear isolators change the ride height.

Mine looked perfect on the rear, so I reused them.....Hope the front are good as well..
