apologies if this has been asked before. I have a 2022 Max King Ranch with 3.31 gears but everything else for the HD towing package. Can I upgrade the gears to 3.73 and then get a tune to recalibrate the ECM? thank you your eedback

You can Forscan it out. But beware it won’t be cheap to have it replaced. If you are 4wd you have to replace both front and rear axle gears. Pricing would be $3k just for labor if you have 4wd and about half that if your 2nd.apologies if this has been asked before.

That isn't that big a jump in gearing. Might want to mess around looking for different wheel /tire diameters to get close.apologies if this has been asked before.

Actually not just 4x2 but also 4x4. My 2017, 2014 and 2011 4x4 HD Tow Limited Expeditions, all rated at +/- 9000lb tow are equipped with 3:31 differentials.Prior to 2018, the HD Tow package on 4x2 Expeditions came with 3.31. It's not an issue for towing. I have 3.31 and tow 7K. I have enough power to keep up with traffic. Sure, more would be nice. But I've towed thousands of miles without issue on the 3.31 gears.

The 4x2 HD Tow 3.31 axles are 9.75 in the rear.If you have the 3.31 rear, you probably don’t have the 9.75 rear axle like the max tow packages have. To properly do the swap, you’d need a full axle for the rear and gear only swap up front if your 4x4.
