Mollencopf kept things simple out back and retained the leaf spring setup. He did make a few interesting modifications to enhance their overall function, however. He went with custom 63-inch leaves and frenched the front hangers into the frame. The rear hangers are custom Johnny Joint swivel hangers. The rear axle is a beefy GM 14-bolt with a spool, Great Lake Offroad heavy-duty diff cover and pinion skid, and Ruffstuff Specialties disc brake conversion.
