3" 3.5" 4" Lift - typically AEV, Terraflex, Synergy.

This stuff is NOT "plug and play". Everything needs adjusting and there is more than enough room to build in strife - or to really fine tune things. The kit is a lot more expensive and takes a lot more time to build.

You need it for 37's, I'd recommend it for 35's though plenty of Jeepers disagree.

I don't think it's enough to leave this with the mod shop - you are on a journey here and will want to be directing how you want it looked after. Quite likely that it is not perfect the first time - these systems need fine tuning. Sensational ability off road, should be great on road. Just more work.

Recommended? Yes but expect to need to work it through.
