Default S10 front diff?

Does anyone know what size ring and pinion an S10 front diff has, also what axles are in them? I think it is a 7.5" R&P and 26 spline axles but just want to verify with someone who knows for sure.

Some of them are 7.5, I think those are 4cyl though, Most 4x4 with a G80 has 7.25" rear and the Zr2 has a 8.5.

I was just not sure about the front...thanks for the info. Does anyone make a clutch type limited slip for the front of these?

all 2wd and most if not all non Zr2 4x4 S-10 rear axles are 7.5/7.625. all 4x4 front axles are 7.25. most zr2s got the 8.5 but there was a few that didn't. depends which options it came with. most xtreme's with the 4.3 came with the 8.5 but that also was variable.

im pretty certain all zr2's came with 8.5 and 8.625 for the rear. The 8.625 was used in 2000 up i believe.

they built some ZR2 trucks without. those were the ones that weren't badged as ZR2s even though they had all the features. mostly early year Zr2's 94-97. i know this as my 95 is built as a zr2 but was not optioned with the 8.5 rear.

Back on topic does anyone make a limited slip for the 7.25" ring gear and 26 spline axles? With the horsepower I have now it is breaking the rear wheels loose and engaging the awd and causing torque steer, I figure a limited slip in the front would solve this issue but I cant seem to find anything...do they even make any upgrade parts for these front diffs? Could I use just the center section from a full size truck?

u can put a lock right in it. http://www.justdifferentials.com/ind...Path=24_45_269 and no a fullsize front axle will not fit. the lock right is your only option for the front unfortunately

Yeah I don't want to put a locking diff in the front, that would probably make it drive all kinds of goofy in the winter...oh well I will just deal with the TQ steer until I can figure something out.

What did the Cyclones and Typhoons do about this problem? Do they have a different size front diff and if so would it interchange with the second gen S10's?

definitely don't put a locker in the weak as hell 7.25 front dif. i would only consider if i had a cast iron front dif which were on certain models. of course you could always swap them though.

So you are driving a bravada or an s10 with the option to have all wheel or two wheel drive by the press of a button dont remember any s10 or jimmy coming with the auto trac system in them.

It's a Bravada, I just said S10 because they are all S10 series trucks and have the same front diff.

Definitely going to upgrade to the cast iron housing, keeping my eye out at the local LKQ for one. They have a list on what trucks came with them on the S10 forums.

Why not change the transfer case or the shift motor to a manual select?

Because it is my wifes daily driver and in the winter I love it being all automatic so she can just jump in and drive.

When she use to drive my truck in the winter she would always be calling me and asking if she needs to lock in the hubs or if she needs to put it in 4x4hi or low...this takes all these questions away, just drive
