F350 Ring Gear Size

Before you purchase any type of shaft, you have to know the precise ring gear measurements. Ford Motor Company made it easy. There are just two sizes to be concerned with when removing the differential. A 10.50 is a very common size. The 10.25 is slightly smaller. The difference in the versions is the ABS brake system that is installed or not.

The full float and limited slip are different. Some of F-Series trucks and E-Series vans were equipped for Track Lok technology. These locking differentials were not standard on every truck that was produced. Keeping this in mind prior to placing orders is really helpful.

Ford Truck Gear Ratios

The one-ton pickup design is meant for heavy hauling. The torque between the transmission, transfer case and rear axle assembly all work in tandem. Changing the stock ratio can provide more or less of needed power for each wheel. This includes the dually and standard rear end.

Crew, Regular and Super cab trim all have varying gear ratios. If you plan to change the right and left side of the differential, you have to know what you already have. Choosing the wrong measurements might decrease the total power available for pulling and towing.


The code that is on the tag inside of the driver side door will have this information. Ford does not print the ratio, but it gives you a code number. Deciphering the information is not exactly simple. AxleGuys.com experts will help you in every way when you inquire with us.
