Custom 4X4 Jeep Zj Under Carraige
When we first met Tommy in Truckhaven, California, his ZJ was already on the trailer with some pretty good carnage: He had busted a control arm and wasted a coilover shaft at the same time. When we saw him again in Moab, he'd fixed everything and boxed in this central transfer case and control arm support frame into a reinforced belly skid. Now his NP242 sits tucked under 3/8-inch steel plate, and his ZJ has a better landing pad. Two-inch DOM lower control arms with 3/4-inch rod ends and 1 3/4-inch upper triangulated arms drop from the crossmember and reinforced unirails, holding a fullsize Dana 70 steady under the 16-inch stroke Sway-A-Way coilovers with a combo of Eibach and King coilovers. The D70 is packed with 5.86 Yukon gears and an ARB Air Locker.

Tommy's front suspension is almost identical to the rear: a matching upper triangulated four-link hooks the Dana axle to the Jeep while it rides on S.A.W. coilovers. Normally you would never want to run a front triangulated four-link suspension because it would cause massive bumpsteer in your crossover steering system during suspension motion, but Tommy has switched to a PSC full-hydraulic steering-ram setup with no solid steering link between the ZJ and the axle, only fluid couplers. The full-hydro steering allows Tommy to turn the Dana 60 knuckles easily. Sitting inside the fullsize '60 is a 5.86 Yukon gearset and an ARB Air Locker to match the rear.

When it's time to go wheeling, Tommy just yanks his doors to save 'em for a rainy day. Inside the ZJ is 1 3/4-inch DOM tubing that Tommy built with the help of R&D Fabrication in Temecula, California. Outside, Tommy has protected the body with Trailready bumpers and Off-Road General Store Supernerf sliders. To make sure the Jeep doesn't spill its fuel, a Trailready fuel-tank skid was implemented underneath.
