The Grand Cherokee and Commander were some of the first vehicles to include Jeeps 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 our exclusive Electronic Geometry Recalibration (EGR) Module, produced by AEV, to provide the properly calibrated 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. Use only with the Superlift® / AEV Cherokee and Commander lift systems.
If you are a Jeep fan, youve probably heard about AEV. Theyve created numerous concept vehicles for Jeep over the years, most recently the Mojave, the Liberty Liberator and the Brute TJ pickup. Normally, their concept rig inspired builds˝ end up being available from AEV, turn-key, to new Jeep buyers.
Nothing was left unaddressed in this Superlift / AEV joint-effort design. Front Lift is achieved, and factory ride quality maintained, by using towers to relocate the tops of the factory coilovers. Thin preload plates install on top of the coilover springs to boost spring rate slightly and offset the increased load / leverage generated by wider tires and wheels. 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 Superlifts Frame Integrated Technology (F.I.T.) design concept, which utilizes super-beefy lower control arm crossmembers that interlock with a full-width belly pan to form an incredibly strong subframe assembly. 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 Jeeps uni-body chassis 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. 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 fairly soft˝ 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.
