The off-road suspension experts at Rancho® are proud to introduce the industry's first suspension system for the Hummer H3. This world-class technology allows H3 owners to rival the off-road prowess of Rancho-equipped H2 models. This evolutionary new package allows customers to upgrade to 37-inch tires *. Among the many exclusive features is a state-of-the-art Rancho/Realift™ torsion bar relocation technology, which eliminates the need to relocate the factory torsion bar cross member - doing away with the need to cut and weld. Rancho® engineers also developed an ingenious two-piece cross member design that allows the installer to precisely relocate the differential - ensuring optimum suspension geometry and zero bump steer - without removing it from the vehicle. Our ultra-precise packaging of the cross member maintains maximum ground clearance; when combined with Rancho/Realift™ technology, this design substantially improves approach and departure angles. 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. NOTE! * This kit was developed using a 325/60/R20 on 20x9" wheel with 5.0" 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, 20" and above we recommend using 5.0" backspacing. Before installing any other wheel/tire combinations, consult your local tire & wheel specialist. NOTE! The dealer installed "Under Body Protection Package" will not reinstall on vehicles equipped with a Rancho Susp System. NOTE! The net raised height achieved with this system is dependent upon the adjustment of the torsion bars prior to installation. Example: If the Rancho System is listed as 3", but the torsion bars on a vehicle are adjusted to 1" over stock, the net raised height will be 2". Shocks not included. Custom order item. Fits 2006-2010 Hummer H3.
