Installed this shackles and spacers on my H3. Shackles are 0.75" longer than the stock ones and much stronger too. Also very good powder coat on them. Spacers are not really needed but I installed them on the torsion key bolts. Now I am at 23.75" in the front and 24,5" in the rear. Measured from hub center to bottom of the fender. I also installed bilstein extended shocks and bump stops. Truck looks awsome and I highly recommend these leveling kits!
