Ive got a 00 crew cab 6sp lifted about 4in on 35 bfg ATs its got stock gears 3 73s but i have a set of 4 10s under a parts excursion so my ?? is it worth the time to swap them I drive my truck on the street a good bit it sees more 60-90 mph then it does anything else but I occassionaly pull a trailer and would like to hook up to the sled. Any pros and cons for this idea. Also who makes a good posi front end for my truck.

I would not mess with it... I ran 37's and 3.73's for years and loved it. Now with 4.30's I am back in the RPM range I should be, but its now louder in the cab and such...

I had 3.73s stock and went to 4.10s. The difference in engine speed at 70 mph went from 2000rpm to 2200rpm, which is good because at 2000rpm and below, my truck was sluggish.
