Dig this: the front suspension cycles through a full 18 inches of travel on stock-width Traction Beams. Mark Kiefer of Southwest Performance built the front radius arms, shock hoops, and engine crossbar. Inside the differential there's an Eaton Performance Detroit True Trac and a set of 4.56 gears. Shane swapped the '90 differential third member for a '80-to-'82 non-C-clip style so he could run any Dana 44 differential on the market. The C-clip-style front diff only allows a factory Trac-Loc.
