Superlift Suspension introduces their 4" Jeep Suspension Lift Kit for the Jeep WK and XK. The suspension lift kit will clear 33" to 34" tall tires depending on the wheel specifications. The factory ride quality is maintained by installing spacers on top of the factory front shock and coil assembly and strut. Thin pre-loaded plates installed on top of the coil springs boost rate slightly to help offset the additional loads created by running larger tires, and firms up what would otherwise be a "spongy" ride.

The upper control arms remain in their factory location and Superlift's unique high-clearance one-piece F.I.T. (Frame Integrated Technology) crossmember lowers the factory control arms and axle housing in relation to the frame. They are seamlessly stitched together by a massive full-width belly-pan that protects the front differential. The crossmember, belly-pan and the load-bearing bracketry are constructed using .25 thick steel plates.

The Grand Cherokee and Commander were some of the first vehicles to include Jeep's Electronic Stability Program (ESP). Creating a true performance lift system with ESP compatibility has been a stumbling block for most suspension manufacturers. Superlift relies on their exclusive Electronic Geometry Recalibration (EGR) module, produced by AEV, to properly calibrate steering input signal to the factory ESP unit. The EGR module also allows for speedometer recalibration, desired when taller height tires and/or different axle gear ratios are installed. The module simply plugs into an existing wiring harness located beneath the dash.
