So i have a 94 Z28 and im looking to give it some more get up and go. From what i've read, getting it re-geared is a magnificent way to get it some more performance, but from what i read that i need to have a series 3 carrier for getting it geared higher. My choice of gearing i want is 3.73 compared to my 2.73's

But my knowledge on the carriers are a bit weak. So what i would like to know is how i can make this gear swap happen. Like were can i get a series 3 carrier, what do i have to do to swap it. Like a step by step walkthrough if anyone would may.

 

Replacing a carrier is hard work, its not a hard job but its very important to know what your doing as you could really destroy your rear end. You could always just replace the whole axle with one from a manual Z28, it should have 3.73s in it factory.

 

^ 4th gens didn't come with 3.73's. Only the M6 cars came with 3.42's. The autos came with 3.23's or 2.73's...

On a more appealing note to the OP:

You can get 3.73 gears sets for the series 2 carrier at SummitRacing.com. They'll hold up better than the series 3 gears sets as well because they're thicker!

Here's a link to a set of series 2 3.73's:

Good luck in your search good sir!

 

Hmm, why did I think they came with 3.73s...

 

Cause you're a noob! Lmao

 

So basically buy the kit and install it without screw anything up. (or let the shop install it for more $$$)

 

The kit will have the gears, new bearings, crush sleeve, etc.. You can buy that but I recommend having someone who is experienced with differentials install it for you. It's pretty easy to mess it up and grenade your rear end if you've never done it before.

 

Well damn I learned about the rear ends from you so...

 

I've told you like 5 times that 4th gens never had 3.73's haha

 

What does B.C. know, he's a "Honda Guy"!
