AEV F.I.T. Performance Series Knuckle 4" Suspension System by Superlift
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. 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. Correct 4-link geometry is achieved with link relocation brackets.
