spring options are getting smaller and smaller.
Synergy still makes front springs, but no rear springs. They say they are progressive.
I ended up with OME/ARB springs to put into the LJ. I don't think they are anything but liner rate. I should have dimensions on how much lift vs stock LJ Rubi this weekend.
I thought about Savvy springs, they say progressive as well. but one size fits all springs didn't feel right, and their lead times as of late have been less than optimal. At least from what I ordered.
The currie springs say dual rate progressive, but 4"
so, not much help. You can always just cut part of a coil off your current springs.
