481 Locking Hubs

The Mile Marker 481 locking hubs are engineered to protect your front axle shafts by allowing you to engage or disengage them as needed. The innovative construction process involves die-casting aluminum into a stainless steel jacket, ensuring both robust strength and superior resistance to corrosion. These hubs provide a smooth, three-quarter turn engagement, which is often found to be more user-friendly than traditional quarter-turn mechanisms. Key specifications for these hubs include a 10-spline count, a 3.437-inch hub bolt circle, and a 1.13-inch axle shaft outside diameter. The housing, dial, and bolt hardware are made from stainless steel for durability and a polished finish. This set is sold in pairs and includes all necessary gaskets, hardware, and a specialized tool for installation. Fitment is specific: these hubs are designed for models with a 10-spline and a Closed Knuckle Axle. They are compatible with 1963-1973 Wagoneers, 1963-1973 J-Series Pickups (including Gladiator), 1961-1971 International Scouts, and various 1942-1973 CJ models. A critical warning is noted for Jeep models equipped with All-Wheel-Drive transfer cases (such as Quadratrac, NP 229); installing these hubs unlocked on such systems will lead to transfer case damage. A part-time conversion kit is mandatory for all-wheel-drive transfer cases when using these hubs in an unlocked state. Mile Marker backs these premium locking hubs with a Lifetime Warranty, underscoring their commitment to quality and longevity.
