I have a 2006 H3 and was looking at the Rancho RS9000’s adjustable shocks I think it was. Also from 4wheel parts and I think the price was only like $500 or so for all 4? that was probably not installed however. I had a set of RS5000’s I think on my old Yukon before I got the hummer 8 years ago and was happy with them as well. Might want to look into those?

 

I put the Bilstein 5100 on my H3T, got them from 4Wheel Parts for under $400 for the set, they were wanting I think $60 to install each shock, ridiculous. I got home and saw how easy it was, just bolts, and did it myself. You will need a super long extension for the rear mounting bolts up by the frame.

my truck is leveled at 23.5", and the ride is firmer, although maybe because my last set was original with 130,000 miles on them and barely expanded when I took them off haha
