OVERVIEW
Choose lift height to see
tire/wheel recommendations
Front lift is achieved, and factory ride quality maintained, by using towers to relocate the tops of the factory coilovers. The lower control arms and differential are relocated via bracketry, then new cast ductile iron steering knuckles span the increased distance from the relocated lower control arms to the upper arms, which remain in the stock location.
The lift system incorporates Superlift's Frame Integrated Technology (F.I.T.) design concept. The crossmembers and pan are contoured to provide as much ground clearance as possible, and stitched together using countersunk fasteners. This extreme rigidity is welcomed, especially considering that the Jeep is a uni-body, meaning that it does not have a traditional rail-type frame.
New steering knuckles and front differential relocation bracketry take care of alignment, CV axle angles and driveshaft angle. Replacement longer factory style anti-sway bar links, both front and rear, ensure proper bar preload.
Rear lift is achieved with new coil springs; a slightly heavier rate was used to improve what most consider a "too spongy" factory ride. Correct 4-link geometry is achieved with link relocation brackets. There are two grades of rear shocks to choose from: the standard Superlift Superide hydraulics, or premium Superide remote reservoir (SSR) shocks, a trick looking high-pressure monotube unit. Both are valved specifically for the Jeep.

A 285 / 70 series tire (32.7" tall x 11.5" wide) on a 8.5" wide wheel will generally clear without modifying the front inner fender. Read the installation instructions for detailed recommendations.

A 285 / 70 series tire (32.7" tall x 11.5" wide) on a 8.5" wide wheel will generally clear without modifying the front inner fender. Using a 305 / 55 series tire (33.2" tall x 12.4" wide) on a 8.5" wide wheel generally requires minor modifications to the inner fenders as detailed in the system's Installation Instructions.

36. Minor cutting and / or welding required.
116. Certain vehicles equipped with Jeep's Electronic Stability Program (ESP) may encounter premature system engagement. EPS system operation is impacted by tire size and wheel offset, vehicle loading and a multitude of other factors. If ESP routinely engages during normal driving conditions, simply disengage the system via the factory "off" button. At time of printing, Superlift is working on ESP recalibration; call or refer to our website for the most current information.
126. New wheel with maximum backspacing of 5.5" is required for installation. Factory spare can be used as a temporary spare in emergency situations.
