Best bet is a 2" budget boost then. Doesn't matter what brand if you go with a budget boost/ coil spacers. You keep the stock springs and shocks, and therefore keep the stock ride. Heard they can be tracked down for $50, but then you'll have to make your own bumpstop extensions if you go with 31's. I got my kit from Rugged Ridge for $100ish and it came with the spacers, bumpstop extensions and necessary hardware for the bumpstops.

If it can't be fixed with squats or fish oil...your probably gonna die (u aware?)
