Replaces all front non-serviceable hub assemblies found on '84 and newer Cherokees, '87 and newer Wranglers.

WARN high strength alloy axles help to increase front end strength and durability. This Conversion Kit is for vehicles changing to a heavy-duty 5 on 5.5" wheel bolt pattern. High strength alloy axles and larger bolt pattern result in a 30% increase in strength. Kit includes WARN premium 1/2 ton internal mount hubs, which are recommended for use with tire sizes over 32". Note: Requires a modified '82-86 CJ7 front rotor. Increases track width by 3/4" per side.
