You didn't fill in your sig. I assume it's a 2nd gen since you posted here. If it's a 4x4 you can take the 4 5/8" blocks out mill them dowm 2" replace with shorter u-bolts. I did this for $25. 00 found free u-bolts at a tire store that came off a new truck they put a lift on. Now my truck sits level when I hook up my 5vr I air up my Ride Rite air bags & the 5vr sits level & the ride is great.
