Mount Logan built the trussed rear Ford 9-inch using a Currie housing center. The housings are trimmed and plated on the bottom for better ground clearance. Ford Explorer disc brakes have an integrated drum e-brake. The rear Yukon aluminum third member also houses 5.38 Sierra gears and an ARB Air Locker. The 4340 chromoly Yukon axleshafts will probably hold up, even with Ed's lack of throttle control. The aluminum Mount Logan upper and lower control arms feature Currie Johnny Joints. Upper control arms are triangulated, so no track bar is needed. Tom Wood's Custom Drive Shafts built both front and rear CV driveshafts. Rubicon Express 4-inch coils, Sway-A-Way 2.0 reservoir shocks, and a Currie Antirock sway bar control the rear of the Unlimited.
