Knowing full well that the stock IFS would never hold up to the trails he planned on running in the Suburban, Lorenzo replaced it with a leaf spring suspension and solid axle. He used a prototype WFO Concepts straight axle conversion kit, Chevy 1/2-ton rear-application leaf springs, 12-inch-travel Rancho RS9000XL shocks, and a modified and flipped sway bar (which was removed in these photos). A limiting strap runs from the differential housing to the Suburban’s chassis to keep the flexy suspension from overextending and causing bind in the driveshaft yoke. The axle is a Ford high-pinion Dana 60 with Sierra Gear & Axle 5.38:1 cogs, an ARB Air Locker, and Warn lockout hubs. The axle is located via a 1 1/4-inch-diameter, 0.250-inch-wall Panhard bar. The big 37s are pointed by a WFO Concepts high-steer system with PSC steering box and a Ford pitman arm. The WFO drag link and tie rod are both made from 1 1/2-inch-diameter, 0.250-inch-wall DOM tubing.
