4.56 GEARS????

[EMMAS POWER STROKE]

I am thinking about putting 4.56 gears in the front and rear of my truck with a good locker for rear. Its 2000 with some mods and a aod.I will be running 37 inch tires . I know the i will be turning more rpm. Is any one running this set up and what have you got out of this gear swap thanks

That is a ton of gear. It's not a gasser. 4:10s would be enough, alot of guys run 3.73s with 37's.

I was wondering the same thing, I have the stock 3.73's with 37's and a little more gear would be nice. However the jump to 4.10's is not enough to justify the cost.

i ran 37's with 4.30's and loved it...

What percent of the time do you tow? How much weight do you tow?

I do some towing i have a 28 foot flatbed, maybe up to 12,000 pounds . I was told it could help egts

3:55's with 35"s. I have no issues and some of the local pullers run that setup.

If you drive on the highway alot you are not going to like 4.56's. Some guys don't even like the 4.30's...

I would stick the tires on it and see how you like it before I did gears.

For that much weight I would do 4.56.

01 Excursion w 7.3 running 37's w 4.30 gears were a little tall, if I did it over again it would be 4.10's and we towed alot.
