what gear ratios should i get?
 

I currently have 4.10s with 33 inch tires. the RPM's at 70 mph are around 2300. they came down when i got the tires but it's still way too high. With the Dana 60 front and the Dana 70 rear, should I get 3.73 or go all the way to 3.54? I don't do too much pulling but when I do it's 10-15 thousand pounds. I don't want to ruin my diesel so that it can't pull anything but i'd like to get around 20 or 22 mpg. i currently get 16

if your on flat grownd go with 354, i but in the hills with weight they suck. Auto or stick 5or6 speed?

What do you think of gearvendos overdrive uint with 4.10 gear set with triple disk lockup?

my 12valve with 3.54 will pull a #10000 up hills easy... 55-60mph !!

i pull 30k+ for a living with 3.54's and a six speed... get about 2 mpgs better than dad towing he has 3.73's... his is a 1 ton mines 3/4.... not to mention somewhere around 10 mpg's better than him empty... his is a 6.7... i love the 3.54... i would like 3.73 for strictly towing but i dont see a swap in my future:rock:

just look at the avatar/prifile pic w/e u call it... lol

3.73 would be a good middle ground

Personally I like 4.10s.

I would go with 3.54, they get better mpg. If your not going to tow very much then 4.10 would sort of be pointless. The only way I would like 4.10's is if I had a really tall over drive, then its best of both worlds.

dump the 4.10 unless you have a farm or are racing it they are pointless

I hate the 4.10 and lost 3.5 mpg on flat ground I want to use it for a paper weight
