{"product_id":"481-locking-hubs","title":"481 Locking Hubs","description":"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.\n\nKey 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.\n\nFitment 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.\n\nMile Marker backs these premium locking hubs with a Lifetime Warranty, underscoring their commitment to quality and longevity.","brand":"Mile Marker","offers":[{"title":"Default Title","offer_id":52689126162744,"sku":"MMK-481","price":299.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687761190.jpg?v=1784902262","url":"https:\/\/store.motormia.co\/products\/481-locking-hubs","provider":"MOTORMIA","version":"1.0","type":"link"}
