Overview

The SuspensionMAXX MAXXCam JR is a torsion bar leveling kit designed for 2006-2010 4x4 Hummer H3 models with torsion bars. It offers an adjustable front lift height ranging from 1 to 2.5 inches with seven incremental settings. This kit allows for increased ground clearance, the fitting of larger tires up to 34 inches in diameter, and the ability to carry heavier front loads, contributing to a more aggressive appearance.

The MAXXCam JR features forged torsion bar keys with an internal gear adjustment mechanism. Constructed from 4140 heat-treated alloy steel, these keys are investment cast to exacting standards, providing durability that surpasses OEM torsion bar levers. The kit includes ShoX-Xtenders to allow the use of stock shocks, maintaining the factory ride quality.

The SuspensionMAXX MAXXCam JR is an adjustable torsion bar leveling kit engineered to provide a 1" to 2.5" front lift for 2006-2010 4x4 Hummer H3 models equipped with torsion bars. This kit is designed to level the vehicle, accommodate tires up to 34 inches in diameter, increase ground clearance, and support heavier front loads, all while giving the SUV a more aggressive stance. Featuring a patented design, the MAXXCam JR utilizes forged torsion bar keys with a seven-position internal gear adjustment mechanism, allowing for precise tuning of the front lift height without compromising handling or ride quality. The keys are constructed from 4140 heat-treated alloy steel, investment cast to exacting standards for superior durability over OEM components. The kit includes necessary hardware such as aluminum driveline spacers, skid plate spacers, and ShoX-Xtenders, which enable the use of factory shocks to maintain a comfortable ride without the expense of longer units. Installation is designed to be straightforward, with estimated completion in 2-3 hours when using the optional SuspensionMAXX Super ‘T” MAXX Torsion Bar Unloader Tool (part# SMX-MT). The kit requires no extensive vehicle modifications. SuspensionMAXX provides customer service and technical support, and the MAXXCam JR is covered by a MAXX Structural Lifetime Warranty. All components are proudly made in the USA. **Fitment:** * 2004-2010 Hummer H3 4x4 (All body styles with Torsion Bars) * The Summit Racing listing also indicates fitment for 2009-2010 Hummer H3T.
