As with every Rancho suspension, there are absolutely no compromises. In fact, our engineers maintained OE steering integrity - and eliminated time-consuming installation steps -- by preserving factory rack-and-pinion location. The system levels the rear to the new front height with premium Rancho low-friction competition leaf spring packs. The result is a true upgrade in handling, ride comfort and performance.

Important Information:
Installation of this system does not allow for re-use of OEM (factory) wheels. This Rancho Hummer H3 suspension lift kit was developed using a 325/60/R20 on 20x9 wheel with 5.0" inches of back-spacing. Use of the maximum tire size 37 x 12.50 will require some trimming of the front air dam/fascia & inner fender well for clearance. Rancho recommends using 4.5" of backspacing on 16", 17", and 18" wheels, wheels 20" in diameter and above can have up to 5.0 of back space. The dealer installed Under Body Protection Package cannot be reinstalled on vehicles equipped with a Rancho suspension lift system.

Shock absorbers are NOT included with this Rancho Lift Kit and are purchased separately using the selection box located above this item description. Rancho currently only offers one shock absorber for use with their H3 suspension lift, their premium brand Rancho RS9000XL 9-way adjustable. The Rancho RS6558B kit is only available in Rancho Outlaw Black!
