The Iron Jock 60 frontend with Rubicon knuckles and disc brakes has hardened 35-spline inner and 32-spline outer axles, CTM U-joints, 5.38 gears, and a Detroit Locker. These are stock width and run JK 5x5 lug pattern wheels. You can see Currie's drag-link bracket. There's an adjustable drag link behind the PSC ram hoses. Also note the Currie towbar attachment brackets and the RockJock skidplate.
