Strange Pro Series Ford 9″ Nodular Iron Case

Nodular Iron Third Member 3.250″ Bore

With a housing manufactured from D-4512 nodular iron – which is significantly stronger than the iron used on factory rear ends.

Strange Pro Iron Center Section Cases are reinforced with extra ribs and additional material; especially apparent in the areas of pinion support and carrier bearing bores. Massive chrome-moly bearing caps are retained by aircraft grade fasteners and solid steel adjuster nuts help to easily and securely setup ring and pinion preload and backlash. Specially engineered lubrication channels make Strange Pro Iron Center Sections the most reliable in the industry. All exterior bolt holes are spot-faced to prevent the possibility of lubricant leaks.
