The H2 utilizes the same basic torsion bar / control arm front suspension design that GM uses on their 2500 / 3500 series trucks. Superlift’s time-proven Bracket Series lift gives a full 6½ lift by lowering (in relation to the frame) the factory upper and lower control arms. Superlift’s new 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 6½ so CV axle angles are kept stock. The system includes a new replacement CV-type front driveshaft to accommodate the H2’s 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 5½ of rear lift with either new coils or spacers for H2s with factory air springs. The system also includes all necessary relocation hardware for the rear link-arms and track bar.
