Hoping this can help the next guy that searches for a suggestion on what coil spring isolators to use...
I am running a 4" coil drop spring in the front and they have a touch of slop when off the jack! Its not alot, in fact, they can only wiggle / rotate until the coil starts to come out of place, then...whatever, its not safe. Plus, my 4/6 drop still has a slight forward tilt, so I wanted to correct that and fix the spring thing.
Enter the Energy Suspension part number 9-6120. I'll even link to it (no affiliation, just saving people time)

If you cut the isolator and shape the part that has to fit into the lower A-arm coil spring notch where the coil works, it should stay put, take up the slop of the 4" drop spring and get rid of my Anti-Mexi-cali lean. Ima finish my whiskey and coke and go install these things.
I'll be back with pics.
