Installing leveling springs? Read This thread

[HEMI®Dart]

When I installed my Skyjacker springs, these weren't available yet.



Polyurethane Coil spring Isolators



Scrap the crappy rubber OEM donuts and upgrade to Polyurethane. There is a rubber like isolator/donut on top of the spring between the tower. This is supposed to absorb road vibration. As long as you have the springs out , might just as well upgrade. They are inexpensive.



2 companies I know off hand make them.

Not sure of the exact size.

FWIW there was another thread

that stated the polyurethane bushings couldn't handle the weight of the mighty Cummins

Hey Bob,



I didn't see that. Do you mean the 2"-3" poly spacers? I was just taking about the 3/8" thick or so isolator/insulater that goes on top of the spring inbetween the tower.



Maybe I'm wrong



They kinda look like this:
