Hey,

Ive got a 92 f150 reg cab 4x4 inline 6: 4.9l, it has stock 3.08 gears.

Question #1
What "size" rear end and gears do I have?

Question #2
I want to re-gear for 38's, I know I need 4.10 or bigger, what is the biggest gear size I can put in the stock front differential and rear end?

Question #3
I am getting a complete front end from the local junk yard (truck was wrecked), so I can pick my front differential from what the junkyard has available...question being, what would you guys recommend putting under my truck? I can get the back axle, rearend, etc assembly also to match... but I dont want to have to modify the truck to fit it. What will bolt right on (front and back if necessary) and be the easiest way out of this situation?

End goal being, 4.10, 4.56, 4.56+ etc gears?


Thanks,
Roger

 

Don't quote me on this, but I believe that the front TTB (twin traction beam) was based on a dana 44 gearset. Your rear axle is probably a ford 8.8"

For gear ratio with 38's I would be looking at getting at least 4.88's
