As title says. How many of you are running stock 3.73 with 35" tires and how many of you have opted to regear?

Seeing if I need to regear if I lift and put 35's on.

I have 4wheelparts.com near me so I can have them install gears if need. TIA

Running 295/65/20s (35.47x12.33 and heavy as ****) on stock 3.73s with no problems. Probably wouldn't even consider it unless going 37s or bigger. I'm getting ~17 on the highway and 14.5-15 in the city. I'm custom tuned as well.

Hey thanks for the fast responses! Yeah I wasn't sure if regearing was a necessary things for the 09-13 f150s yet. Seems everyone's doing just fine on the 3.73's with 35s

What is the code to know the truck has 3.73?

If its an FX4 it comes standard with 373's. don't know about the other packages. FX4 is what I have so its what I know. BTW, I'm running 35's on 20's on a tuned Ecoboost screw. No problems at all (even while towing).

XLT 301A diesel actually exists. Special Order. Maybe a fleet customer backed out. Has an August invoice date. Not a bad deal.
