Hey guys, I have a couple of questions about regearing.. I have little knowledge of them.. so if you could help me out with it I'd love it...



I have a 7.5 axle and a 3.73 ratio.. I have 33's and I think I need to regear. Is this all that's needed to do so?

also, is this a good ratio size? Will I lose or gain mpg with these??

 

You also need a rebuild kit. That's a fine size. You will lose MPG.

 

really? i was always under the impression that regearing your truck would increase mgps??

 

Oh. I guess you are have the tires on. Adding the gears, according to everyone on this forum, shouldn't change your MPG. I was thinking that you hadn't done the tires yet.

 

My understanding is that when you get numerically higher gears it puts more power at the lower speeds. Essentially this mean that city MPG would improve and highway MPG would decrease.

Have you considered 4.30 gears?

 

yeah.. i don't really care about the power as much as I would like my mpg to increase...
What gear size do you guys recommend? And yeah, I have the tires already mounted

 

mpg increasing depends on what kind of driving you do...

If you drive 90% city you want a numerically high gear (EG: 4.56).
If you drive 90% highway I wouldn't re-gear.

You need to factor in how often you drive surface streets versus freeways, and what kind of driving you do (IE: speeds, acceleration etc.).

 

yeah, i do mostly (75%) city driving, and i go offroading about once a month, so that is part of my freeway driving of the month, among a little here and there..
my driving habits are badd.. i speed a lot and i accelerate fast off of green lights.

hmm

 

too bad you dont have an 8.8, i want to go back down to stock gears and smaller tires

 

 

I actually just found this:
