Are there any companies making 4:10 or taller gears for the F-450? Mine has 4:30's (the highest I could get from Ford) and it's just too deep for highway cruising.

This truck is going to see a lot of highway miles (and a lot of miles in general) so I think I will make up for the cost of the gear swap in fuel savings and wear on the motor (i.e. not turning 2500rpms at 65mph) :bang
 
If a US Gear would work.....it could be an option? I believe you can get them up to 20 over, I think.
 
A 3.90 would be a good choise.. I dont think you would see much from a 4.30 to a 4.10. Dont know where to tell you o look though. Good luck
 
what are the axles in a 450 again? Is your truck 4wd? If so, I'm sure you can make some decent money back with them for sale on here and the web. Many people would like to use those but they're only available through Ford. Regardless, I'm sure you can get a 3.73 as you can get it for a D60, D70, D80 and a Sterling 10.5, and you have to have one of those.

3.90 would be great... I'm gonna put in a call to US gear tommorow

it's a Dana "Super 60" front and a Dana 110 rear I belive.

i have 4.30 s in my 350 and 75 fr me is right at 2900 rpm. and where the wife drives it sure does scream 3100:ft:

i to wouldnt mind dropping in a aux tranny to get me some lower rpms at cruise speeds when empty
 
Front not a problem....rear, hmmmm...i dont know of where you would get them; maybe someone else does.


Id rather just throw bigger tires on it! lol
