I think the 33-12.50s are just a bit too much though, even if they do look good. I'm running 4.10 diffs, but I think I should have gone for a bit higher ratio; in a headwind on the highway you can't pull fifth gear at normal speed limits (2WD of course).
I LOVE big pickup trucks, but the advantage of this in mud or snow is its short wheelbase. I can always pull a trailer if I need extra carrying capacity.

PS: Gas mileage with this 4L engine sucks anyway, so I'm not too worried. Might change it out for a 4BT diesel down the road, but this engine's still strong so I'll leave it for now. |
Hi Jif..
You say...
"I'm running 4.10 diffs, but I think I should have gone for a bit higher ratio; in a headwind on the highway you can't pull fifth gear at normal speed limits (2WD of course).
If you put higher ratio diffs in,both of course..say 3.71:1..you would be in second gear in a head wind...that would really suck..
But your overall gas mileage would improve..mucho..
The old flat head Fords..'49-'54..had 4.11:1 rear ends.. they were the ideal ratio for making the old girls "Peel"to impress the chicks at school..no top end..but fast enough to scare a fellow..That is why they came out with overdrive.
You may want to look at your transfer case instead.This would be your best bet...change the input gears..

There are 40 something gear variations in the transfer cases..so there is something there for you..
Changing your diffs would not be the answer..
