Up front, the factory IFS is long gone. Now there’s a custom, high-pinion Currie RockJock II axle sitting front and center. It’s made from ductile iron and has 3¼-inch-diameter axletubes, Ford F-450 knuckles, and a custom diff cover. Inside, it has Currie 4340 chromoly axleshafts and 35-spline stub shafts, Motive Gear 4.88:1 ring and pinion, and an ARB Air Locker. It also has Warn Premium hubs and Wilwood disc brakes with Wilwood Dynalite four-piston calipers. The axle was fitted to the FJ using an All-Pro Off-Road Solid Axle Swap Kit, which also converts the suspension to a three-link coilover system. The steering system consists of a Howe Performance Ram Assist with 2x8-inch hydraulic ram; All-Pro pitman arm; All-Pro 11⁄8-inch-diameter, 0.250-inch-wall drag link with FK chromoly spherical rod ends; and an All-Pro 1¼-inch-diameter, 0.250-inch-wall tie rod with FK spherical rod ends.
