Another Pro Rock 60 brings up the rear. Dynatrac offers its customers their choice of brakes and bolt patterns. Gary went with Explorer-style discs and a 5-on-5-1/2 bolt pattern. Like the front, there's an ARB Air Locker and a 4.88 gearset behind the beefy diff cover. There's a Gen-Right gas tank and skidplate aft of the rear axle. Skilled driving and the generous 37-inch tire size means there aren't too many scratches on the Gen-Right skidplate, but it's built to take it if the rig's tail does meet a boulder the hard way.
