Zack Vaughn was our trail leader for the day in his '93 Wrangler. With its 108-inch wheelbase, it made all of the climbs seem easy. You may have noticed that this thing looks nothing like a YJ, and you'd be right. The only parts Zack left stock were the frame, tub, and steering column. We were actually surprised that the 2.5 squirrels under the hood had enough oomph to spin the NP435. From there, the 5:1 Atlas II splits power to the front Dana 60 and rear 14-bolt. Somehow the front axle manages to keep its 3.55 gears and a Lock-Right together while the rear runs mismatched 3.73s and welded spider gears. A custom four-link rear suspension and three-link front make room for the 40-inch Maxxis Trepador competition tires on 17-inch KMC Enduro beadlocks.
