4x4 gears

[Robert.K]

About to upgrade my gears from a 3.73 to 4.10's. my trucks a 4x4 so i had a couple of questions about it first.
1. are 4.10's the biggest or best option?
2. do i have to put gears in the front and rear Differential?
3. how difficult are they to put in?

Thanks for any support given

1. Not the biggest but may be the best depending on tire size.
2. Yes.
3. If you've never done it and want to, get help from someone who's done it a few times. It's not rocket science but it needs to be right.

Thanks man for the input. I dont plan on putting them in myself, just curious. do you know if 4.10's fit in the front and rear?

if you have 3.73's now, i bet you won't see HUGE gains going to 4.10's....not worth the cash outlay anyway.

How tall are tires?

 

[Robert.K]

32 inches, 24 in rims on a 305/35/24 tire. i need to replace the gears in my front diff, so looking to do the front and rear while its up. but i would like to upgrade if i possible. dont know what the biggest gears that can fit in our differential cases.

I though about his when I had my rear go out. My mechanic said it wasn't worth it for being a daily driver. Not that much gain and higher RPMs on the highway. I guess its up to you though and what you want mileage/highway wise.

I have 3.42's with a G80, and 31" tall and I am going to do 4.10's. If you swap, and your taller, larger rotating mass with bigger rims, I say 4.56's.
