Gears I would do 4.10s or 4.30s. I wish we had that in our 02 F250 but the 3.73 Limited slip does fine but we are running 285 75 R16s but we do pull heavy loads to. I want to upgrade the transmission cooler on ours too. I belive if you get a tuner then it will do great for shift points on the transmission. Everybody here recomends the Mikes 5 star tuner but we don't have that we have the Bully Dog Chip and it does great.

Our '09 F-250 SD automatic has 4.30's with the stock 245/75/17 tires. It's turning 2000 rpm @ 60 mph.
As someone else suggested earlier, if you're gonna' go with a taller tire than the original equipment you'll want to go with at least a 4.56 and a 4.88 would probably be better.
Alaska prices are spendy for anything... but three and a half large... but that was for everything installed, new seals, new bearings, new gears and a new locker. Actual gears were only $259 each set and the locker is 807. Bearings and seals were another 500... you get the idea... a little less than half was Labor.

Ouch.. I've got to get a bid for that exact swap, was hoping you'd say closer to 2
I'm going to drive it Friday, and will see how the Ex drives. If there seem to be any want of power, I'll order up the gears. Looking to go with the 4.30's.
Any one else like or dislike their 4.30's with their V10?
I have a '08 F350 crew cab, long bed with 275-65-20" tires which are 34.2 inches tall. I have the 4:30's and sometimes wish I had 4:56's especially when towing, just for that extra oomph. Personally I would go with the 4:56 gears.
Great discussion! Wondering where I figure out what gears I have in my 2000 F350 V10 truck. I think they are stock, but I am the 3rd owner and cannot be sure.
Seems I cannot upload a pic, might need to pay for membership to do that, new here so figuring it out. I did add a pic to my garage so the sticker pic should show there.
