How do I know what gears my f250 has?

How do I know what gears my f250 has?

There’s no question, the easiest way to identify the axle and gear ratio in your truck is from the door sticker. If you open the drivers door and look at the door jamb, you’ll see a sticker like the one shown below: You’ll see that the area labeled (F) is for the Axle Code.

Where does the pinion gear go on a F250?

The driveshaft then runs to the differential pinion gear. This pinion gear turns the ring gear, which uses another gear reduction process to turn the wheels. This is the same concept for the front and rear differentials.

What should the gear ratio be on a F250?

A 4.30:1 gear ratio is very effective and popular in this division. Off-Road Only: For off-road only applications where top speed and comfort are of no concern it’s open season. Applications running gears with ratios lower than 5:1 is nothing outlandish for these types of F-250s.

What kind of gears do I need for my Ford F 350?

The following gears, lockers and install kits are available for 2008 to 2010 Ford F-250 and F-350 Super Duty trucks with Dana 60 front axles and Ford Sterling 10.5″ rear axles. Note: Ford 10.25″ long pinion gears are also compatible with the Ford 10.5″ axle when a Ford 10.25″ master install kit is used.

What kind of differential does a Ford F-250 have?

The 1994-1997 Powerstroke equipped F-250 and F-350 trucks featured a Dana 60 assembly up front and either a Dana 80 or 10.25″ out back. The 10.25’s were reserved for single rear wheel (SRW) applications, where the larger 80 was used in all duallies (DRW).

The driveshaft then runs to the differential pinion gear. This pinion gear turns the ring gear, which uses another gear reduction process to turn the wheels. This is the same concept for the front and rear differentials.

A 4.30:1 gear ratio is very effective and popular in this division. Off-Road Only: For off-road only applications where top speed and comfort are of no concern it’s open season. Applications running gears with ratios lower than 5:1 is nothing outlandish for these types of F-250s.

Which is the best gear for an F-250?

An updated ring and pinion gear is a favorite mod among F-250 owners. Like your typical F-250 mods (cold air intakes, big tires, lift kits, and so forth) the differential ring and pinion gears contribute to some serious performance gains.

Where do I find the factory number on my differential?

This number is stamped on your right hand side axle tube. It’s a number like 603XX-X, 604XX-X or 605XX-X. With this number you can tell exactly what components the factory used in the assembly of your differential.
