This site is for high pinion 9" Ford front and rear differential center sections ( third members ). It uses actual 9" Ford style gears for more height and more gear strength than a high pinion Ford 8.8, high pinion Dana 44, and high pinion Dana 60. The Hi 9 will be lighter weight and sometimes less money than an aftermarket high pinion Dana 60. It will fit as a direct replacement in existing 9" Ford housings without modification.
The Hi9 was originally designed for street use so daily driving is NOT an issue. It just turned out to be strong enough for competition use also.
If you're interested or have questions, feel free to contact us.
Stock gears and/or cases will NOT work with these.
