Problem finding 4.30 gears
I have a 2020 F250 7.3l gas with the 3.55 gears. I recently lifted it 6in and looking to add 37in tires. I do tow a boat and travel trailer and know that I can’t add 37s with the 3.55. I have been trying to find 4.30 gears and haven’t had any luck. The dealership has the part numbers I need but it doesn’t show any kind of stock for either front or rear. Has anyone with that engine had any luck re-gearing to 4.30.

Might be able to find aftermarket in the 4.56 - 4.88 area, which would work out good with those 37's. Don't know how easy it would be to program everything to get along though. As to the Ford 4.30's, I'm sure they're allocating almost all of them to new builds.

I’ve tried that and the part numbers do t pull up anything. Dealership gave me the part number but it’s not showing up as a valid part number on their side either.

having ordered quit alot of oe parts for numerous vehicles, i go online and look at the parts diagrams myself without speaking to any dealers. this eliminates any errors or bad info they might have. 4.30 oe gears look to be readily available for the front and 10.5 rear. the dana rear isnt even shown so im guessing theyre not even offered for sale at this time. being a new axle and most people dont regear to a factory ratio, probly isnt much demand right now for a surplus of 4.30 gearsets

I ordered my 7.3 with 4.30's and since ford seems to be delaying 2022 orders now I may have to compromise and find a 7.3 with 3.55 off the lot. Thats my plan too. Wait for a wrecked Tremor and just pull the axles.

Yes it's that easy. Both axles have a huge aftermarket. If you had the M275 rear then I would say the aftermarket is limited but you have the sterling so more options.

As mentioned you may want 4.56. I certainly would with 37s and the work needed to install them; also a front Elocker.
I would locate a good shop to help.
May even want 38s and 4.88 gears with your 6 inch lift.
