im saving the cash to get my swap done. i have 3.55 stock and with all the calculators 4.10 is going to put me at 1950 rpm at 65mph which is higher than stock but i think it will be better to pull the sled trailer and boat as well as more gas friendly around town where it spends 95% of its life
I have done this before on a dodge durango that I went from 3.55 to 4.56. I didnt upsize my tires, just looking to get into the power band faster. It wasnt too bad on highway as long as it was under 60. It would really launch out of the hole too!
i would go with 4.56... my plans are for 4.88s...
yeah I am leaning towards the 4.56. going from 3.73 to 4.10 I dont think would be enough of a difference to warrant all the money spent to change them. I will be adding a Richmond Locker when the new gears go in but thats still a few months down the road.

I think 4.56's are almost mandatory for 35"s. Go with those
Yeah from doing some research 4.56's seem to be the right choice and even saving you mpg's in the city. Now thats something else that I need to look into. Bastard
Having done this before on a previous truck, it comes down to a tradeoff. You will lose MPG on the highway but gain a few in the city if you keep your foot out of it! The 500 mile break in is grueling! Took me over a month the last time.
Yeah I remember that break in with my mustangs lol. 4.56's dont seem to be to expensive though...
