I currently have the 5.4L with 3.55 gears and 35's....it came with 17's.....my max trailer weight is 8300lbs(more like 7500lbs with 35's)........

If i went with say 4.10's or 4.56's would it get my tow rating back up to stock or maybe a little bit higher???? I pull 3 quads on my tandem axle trailer(not sure on weight) and i just don't want to hurt the truck

i would go with 4.10 if you dont haul daily. it would be a good mix and give you more low end and not kill your mileage. it might bring it up a tad from what you have now.

alot of it depends on your tranny, i have 355 gears too but they get real low behind a 4 spd bulldog, i have video proof if you need it, its so low i dont even use my 1st gear in 2wd even when i'm pulling 3 ton behind it, its just that low with that tranny

all the gears really do is change your RPM's at a certain speed due to you tire size, so you wont "gain power" but it will let your trucks power get the ground more efficently.

ive used this a few times. it kinda handy.

what he said...all it does is change the amount of horse power getting to the wheels, now, if i had a 5spd i would get about 5mpg more but i would lose that power getting to my wheels, not alot but enough to have to start using 1st gear.

okay kool....so let me see if i get it.......it doesn't really matter which gears i go with because it won't really make my rating go up it will really just get me as close as i can to stock and be able to pull like i used to be able too???

if youve got 355s, just go back factory, or, if you do alot of offroad or towing, and dont mind getting a few less mpg's, get a 4spd bulldog, if not go back factory, get a tow package put in your tranny and your good to go

yes you usually try to get back to stock with a gear swap. if you go a little taller than what the stock setup you will have more low end power but get less MPG. i would go with 4.10's if you just do ocassional towing to save MPG.
