The H2 utilizes the same front torsion bar / control arm suspension concept that GM introduced in 1988. Superlift offers our proven bracket style lift method, instead of replacement knuckles, primarily because using knuckles on the H2 creates a substantial increase in front tire track width (this is covered in-depth in the introduction text). Lowering the factory upper and lower control arms in relation to the frame brings ride height up. By utilizing the factory control arms and torsion bars, we are able to retain stock alignment geometry and ride quality. New Superlift control arm brackets tie into crossmembers that span the distance between each frame rail to form an exceptionally strong assembly.

The front differential assembly is also lowered a full 6 inches so CV axle angles are kept stock. The system includes a new replacement CV-type front driveshaft to accommodate the H2 full-time 4WD, and provide smooth, vibration-free operation Steering linkage geometry is addressed by relocating the factory centerlink, which keeps the tie rods in phase with the lower control arms. A greasable stabilizing link regulates centerlink movement, and reduces the load and stress transmitted to the pitman and idler arms. The H2 factory rear suspension is either coil spring or air spring. Superlift provides 5 inches of rear lift with either new coils or spacers for the H2 with factory air springs. The system also includes all necessary relocation hardware for the rear link-arms and track bar.

Foot Notes:

7- With single exhaust, a new, reformed section of exhaust crossover pipe is required to clear front driveshaft.

27- Special puller tool is recommended to load/unload torsion bars.
