REAR GEARS

[Alwaysreadyrob]

Can anyone help me determine if a 1994 F 2507.3 turbo IDI has 411 gears and a Dana 60 front end ? It is a 4x4 also.

If it's got the original axles, the tag on the door jamb should have the axle code... also a D60 straight axle is pretty obvious to look at compared to a D50 with TTB.

You can tell by the tach too. At 60 mph the 4.10 rear is turning about 2100-2200 with the stock tire size. Considerably lower with a 3.54...

Unless your front axle has been swapped out, all F-250's came with the Dana 50 TTB. I'll attach a few pics that'll help you see the difference between the two. As for the axle ratio, as @DrCharles said, find your axle code and google it, that'll tell you what ratio you have.

The first two pics show my old D50. Notice that it pivots in the middle.

This is the D60 that replaced it. Notice that it's solid all the way through.

If you don’t have stock sized tires you can use a gear ratio calculator. I like this one http://www.grimmjeeper.com/gears.html
