Rocky Mountain Suspension Products, Hummer H3 suspension lift kits

Tuff Country EZ-Ride Suspension's Hummer H3 lift kits are more than your average lift kit. All lift kits are engineered to give the highest quality & best value on the market. Compare components of a Tuff Country Hummer H3 lift kit to that of other manufactures and you will be convince that nothing beats a Tuff Country suspension lift kit. Many others cut corners with inferior components or lack of many important pieces. Tuff Country does not cut those corners and provides a quality complete system engineered to give the best ride quality and durability money can buy.

The Tuff Country EZ-Ride Suspension engineering team has designed this suspension system around new driver / passenger side steering knuckles and front / rear cross members. These cross members are connected by a heavy duty skid plated designed to protect the front differential and stabilize the cross members. This superiorly designed kit also allows for the torsion bars to remain in the factory location, eliminating relocating of the stock torsion bars. Front sway bar end links use a heim-joint end that eliminates any binding in the front sway bar. Also included are differential relocation brackets, performance bump stops and rear u-bolts.

Rancho Hummer H3
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. Also included with each kit is Rancho's Hummer-inspired skid plate armor to protect the front differential. Additional H3 Features as follows:

Two-piece cross member for maximum ground clearance and ease of installation.
Front differential drop brackets correct pinion angle for minimized driveline vibration which 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 up to a 37" tall tire and 20" wheel. Rancho recommends 4.5" BS on 16", 17", 18" wheels. 5" BS on 20" & larger wheels.
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.

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 result is a true upgrade in handling, ride comfort and performance
