Derek Sanderson’s ’91 Wrangler rides on a spring-over conversion and a set of home-mixed leaf packs. Underneath those springs are a front swapped-in Wagoneer Dana 44 and rear AMC Model 20HD axles stuffed with 4.88 gears. The front axle has a Lock-Right and Yukon axleshafts, while the rear benefits from an Auburn Ected locker and a full truss. The spring-over conversion clears the 35x12.50R15 Maxxis Big Horn tires with no problems. Under the hood lies the factory 4.0L engine, AX15, and NP231.
