what axle ratio?
Hi Everyone,
I have a landscaping company in San Francisco and currently drive an 03 f350, 6.0., cab and chassis. I do 90 percent of my driving in the city and pull a dump trailer in excess of 16K up and down the hills of SF on a regular basis. I bought the truck new, am on my 3rd tranny and second rear end. I think its because it has 3.31 rear end and too much pressure on the drive train.
Anyways, I am buying the new 6.7 and can't decide whether to go with the f450, 4.3 gear ratio or go with the 4.8 gear ratio which would require that I get the f550.
Also, although I want the new truck now, should I wait 6 months or so for the 2012 or does it not make a difference?
Thanks all,
Paul

I have a 6.0 with the 4.88's, works fine for that setup, but on my ordered 2011 6.7 I skipped the 4.88's in favor of the 4.30's. seems better as the motor makes more torque at lower rpm and it does not rev as high. I think that 4.88's would be overkill and keep it reving out of its power range.
