I believe that is a limited slip differential with 3.55 gears
I believe you can find the axle code on one of the stickers on the end of the drivers door - then the code is used to find out what differential gearing your F150 has
( H6 ) - is a 3.73 limited slip differential on a Ford truck / SUV
Ford axle code B6 is a ( Ford limited slip / traction - lok differential with a 3.73 ratio )
Axle code 12 indicates a 2.73 conventional non positraction differential. Many people that tow a lot go with a 3.55 and those are axle codes 19, 29, 39, 49, and 69.
The inter axle differential (also called a power divider) is an integral shaft in the forward axle. That shaft is the input for the forward axle and also the rear axle with a differential separating the input from the output allowing for a difference in speed between the front and rear axle.

Conventional non-Positraction Differential 3.55
I believe that is a 3.55 conventional axle ( non - limited slip )
( H6 ) - is a 3.73 limited slip differential on a Ford truck / SUV
19 Conventional non-Positraction Differential 3.55
The rear differential is where the driveshaft meets the axle. Its right in the middle of the axle and is about the size of a basketball.
