where to buy gears

[blackout07]

I would without hesitation do 4.88s with 35s to 37s. I much preferred my truck with the 35" tire and 4.88 combo to the current 37" tire setup. You could go with 4.56 from 33s to 35s depending. But honestly for the op, if you stick with a true 33 and you currently have 3.73s I wouldn't worry about it. It really all depends on how you drive and what you want.

305/?/?

305 70 17's nittos down to 265 70 17s for the winter

My truck with 33x12.50 Toyo MT and 3.73's wasn't bad at all honestly, I wouldn't spend the money to re gear unless you're thinking 35's.

[travishale84]

i had 285 70 17's which were 32.8" and are actually taller than "33's" which most come out to be 32.6". 305 70 17's are 33.98" tires (my terra grapplers) tags read 34x12.5-17. i know the 4.8's are turds, but mine really lacks whatever low end it used to have. if you guys think that a re gear for 34's is a waste. perhaps i will skip it over. wear out my 305's and put some 285 MT's on it...

[blackout07]

It's not a waste, it's just hardly necessary. But if you have a 4.8 I'd be willing to bet you have 3.42s. If that's the case I'd regear if you have the cash to spare.

[travishale84]

any way to tell what gears i have? i lost my window spec sheet at some point.

Glove box. there will be 1 or 2 G codes. G80 wouldl be locking diff.

 

GT4 is 3.73

GT5 is 4.10

GU4 is 3.08

GU5 is 3.23

GU6 is 3.42

[cparks555]

I should have clarified that mine is the 5.3 with 3.73's, didn't realize you were talking about the 4.8 and 33's.

[travishale84]

yea im jealous of all the 5.3 owners.... especially the ones with the 6 spd. at the time i couldnt afford a 5.3 with the 6 spd. BB tune definately helps my next truck will definately have a minimum of a 5.3. im dreaming heavily of a 6.0-6.2 in my future. that or a nice camaro. haha. i appreciate all the info

and im pretty adiment that my tires are 34's

[travishale84]

so i opened up my glove box and found that i have a g80, which i already knew and that i also have 3.42 gears... now why would gm put 3.42s in a 4.8 and 3.73s in a 5.3? so someone with a 4.8 doesnt wax a 5.3 at a stop light?? haha

[blackout07]

Well throw some 4.56s in there with a quality tune and "wax" 'em. Nothing quite like a jacked up truck that can move.

I have 3.23's in my truck with the 5.3, I'm hoping for 4.10's sometime next year.

I plan on ordering a pair of 4.56 given I have the 5.3 w/3.42 gear currently in mine when I PCS back to the U.S. next year.

I'd go 4.88 in your case.

[DwelveAT]

I'd go 4.88 in your case.

Well you seem to know a lot about gearing so I will take your word on that. Any particular reason on why a 4.88 would be better over 4.56?
