or read about the BFG Blazers:

Wanting to dominate off-road racing, Chevrolet approached Parnelli Jones in 1976 with the opportunity to create a very special race vehicle–the BFG Blazer. Of course, Parnelli accepted the task and took to the project with his build team, creating the famed Blazer with their extensive knowledge of the off-road race world at the time.

Unlike other off-road racing rigs of its day, the BFG Blazer made use of a full tube-frame chassis, custom one-off suspension components, a fiberglass body and a Big Oly-inspired wing across the back of the roof. Built specifically for off-road competitions, the suspension system of the BFG Blazer was a custom IFS system with unique stamped A-arms, Summers Brothers hubs, and Gabriel shocks in the front. Out back, the truck made use of a unique six-link system and Jacobs Ladder setup fabricated and massaged by Dick Russell and Jones.
