what kinda rpms does each gear turn on the highway roughly. ive got a 99 2wd with 3.55 and was curious about a gear swap

 

doing 65-70's with my 35's with 4.10's i sit dead on at 2grand in OD.. you gotta take into consideration type of tranny, and tire sizes ttoooo

 

i got the stock auto tranny and 255/70/15 if that helps any

 

heres a good website with few calculators

thanks rip.. i was trying to look for that link..thought i had it bookmarked

 

yup, I go to it for some info quite a bit. quick question. say you had 1: 3.55 + 265's and 2: 4.10 + 285's. Would having 2 feel as if you were using 1? Just trying to see if 4.10 gears would be best, much better than 3.55 and I think the next one up, what is it 4.56? would be kinda overkill, with the 285's. (might sound confusing lol).

 

Are gear swaps easy in a Dodge 4x4?? I may have to go from 3.55 to 4.10 because my 5th wheel is pretty heavy and the truck might be working a little too hard on the hills. Gear swaps in a ford aren't too bad but this is my first dodge.
