Replaces all front non-serviceable hub assemblies found on '84 and newer Cherokees, '87 and newer Wranglers. This conversion kit improves the vehicle's flat towing and reduces driveline wear by allowing you to disengage the front driveline completely. WARN high strength alloy axles help to increase front end strength and durability. This Conversion Kit is for vehicles that retain the stock 5 on 4.5" bolt pattern. It allows you to use WARN flange mount standard hubs on the factory bolt pattern. Not recommended for tires larger than 32". Note: Increases track width by 3/4" per side. Full cast rotors must be purchased and the rotor pilot hole must be machined to 3.575 ± .015 before installation (Full cast rotor ITT PN 65225, Wagner PN BD125039, Raybestos PN 7142).
