Mile Marker Locking Hubs 1974-1976 J-20

Mile Marker Supreme Locking Hubs help to engage/disengage the front wheels from the front axle shafts, protecting the shafts from wear and tear. Made using a new process of die-casting aluminum into a pre-made stainless jacket these hubs provide strength and corrosion resistance. Built to exacting standards, they feature three-quarter turn engagement, which is easier to engage than quarter-turn hub mechanisms.
WARNING: If you have a Jeep that is All-Wheel-Drive (like the Quadratrac, NP 229, etc) and you install these hubs and unlock them, you will burn up your transfer case. You must install a part-time conversion kit on all-wheel-drive transfer cases to use these hubs unlocked.
