Looking at the passenger side of the axle (U.S. passenger, that is) you can see the outside of the 35-spline Warn Premium locking hubs and the high-steer arm bolted to the knuckle, which will keep drag link and track bar angles down. The Ultimate Dana 60 front axle uses an old-school rebuildable spindle and bearing design like a traditional Dana 60. Also, the axletubes are massive, with a 3 1/2 inch OD and a 0.370-inch wall thickness. Axleshafts are 35-spline chromoly units with full-float axle ends and spindles. Front and rear axles are available with either an ARB Air Locker or our choice for UA2018, an Eaton ELocker.
