I went with ESPO for my wagon. In the 16+ yrs (
) they've been on there, what was 1" over stock is now level if not a little lower. At the time, I didn't make any special requests, just went with what was spec. Lady on the phone was SUPER helpful, and the springs arrived earlier than expected.
The only issue I had (though no fault of ESPO) is that I kept the iso mount, so I had to change out the locating stud in the new springs.
The two years before I stopped daily driving my wagon, I threw on a set of coil over shocks.
I would use ESPO again, but this time I might ask about different rates, number of leaves, etc.
As an aside, to give you an idea how bad the original spring were on my wagon, the 1" over stock spring raised the back bumper about 8 inches......
