F450 Axles
f450's from 1988 to 2001 have a dana 80 rear axle and a dana 60 front axle. spline count up front = 35, spline count in rear = 37
your gears in there could also be 5.13s or 5.38s
just curious-what were you thinking of putting in there and why? theres 2 f450s in my family and I love em

your revving high because that big bad engine is begging for a load to haul
seriously though, the truck is set up to be running around either pulling something or carrying something all the time. f450s are made to be working all the time, they are much more heavy duty than an f350. f450s cruise nice on the highway with a few tons on the back or pulling a heavy trailer. your taking away alot of the capability of your truck by going to a higher ratio IMO. if you go to haul 5 or 6 tons on the back or pull a 10 ton trailer or do both at the same time you'll be wishin you had them 4.88s or even lower because the truck is fully capable of moving that weight. the truck might be overkill for what you need it for. but you know your situation alot better than i do so do what will benefit you the most. just something to think about :-)

I don't think you can go any faster than 4.56 in the Dana 80. Mainly because the ABS tone ring on the carrier would be too far away from the sensor(which is externally on the diff. housing) to pick-up a signal to speedo & ABS system.
I have been this route before. If you can't believe this, get the B/M # off of you diff tag (should be something like 605249-3) and call Dana Technical in Toledo, OH. Phone# 419-866-3960. They will be able to tell you what You can convert to. I think you're stuck with 4.56. Gearman

You can go all the way down to 4.10's on the rear carrier, no trouble with the tone ring location, you will need to change the front carrier, it's break is 4.56 up, 4.10 and down. Other choices for rear gears are 4.30, 4.63, 4.88, 5.13, 5.38. But since you have a 4wd 4.10 is your only other choice, the odd ratio's are used in the 2wd F-450's.
