Rancho RS6558B Suspension System 4" Lift Kit 2005-2010 Hummer H3 AWD Front Torsion/Rear Leaf

Rancho RS6558B Suspension System 4" Lift Kit 2005 2006 2007 2008 2009 2010 Hummer H3 AWD Front Torsion/Rear Leaf

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. Also included with each kit is Rancho's Hummer-inspired skid plate armor to protect the front differential. Features Two-piece cross member for maximum ground clearance and ease of installation. Hummer-inspired differential skid plate armor. Front differential drop brackets correct pinion angle for minimized driveline vibration Maintains factory location of rack & pinion. Preserves OE geometry for easy alignment, zero bump steer, and optimal ride & handling. High-clearance aft braces for added strength while maximizing ground clearance. No drivetrain or exhaust modification. Includes new rear low friction competition leaf spring packs. Allows for use of up to 20" wheels. Allows up to a 37" tall tire. Rancho/Realift™ technology for no torsion bar relocation results in increased ground clearance. The industry's highest quality design, CNC- machined, cast ductile iron steering knuckle. Allows for reuse of the OE front skidplate. 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.

Installation of this system does not allow for re-use of OEM (factory) wheels. * 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. 218 - The dealer installed "Under Body Protection Package" will not reinstall on vehicles equipped with a Rancho Susp System. 18 - 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".

Notes
