I'm looking at putting some 3.70's in my 9 bolt, and just wondered if anyone knew where i can find the gears i'll need

thanks

 

I have a 9 bolt rear and from what I've been told by many people... the only place to get gears is through GM and plan on paying out the *** for them. A friend of mine with a 9 bolt in his Iroc looked into getting new gears for his.... over $500

a memeber here, has 3.73's and 4.10's for sale.

Mista is right, Miles (with 427 in his nick) has a source for some gears. Here's another one:

SLP makes 3.70 Gears for the Australlian Built Borg & Warner 9 Bolt 7.75" rear axel.

Last time I checked SLP doesnt sell the 3.70 gears anymore.

Do a search on this forum and you'll find all the info you want on 9-bolts.

I've currently got 4.10 gear sets and series 3 carriers for 9 bolts. Send me an email if you are interested.

Currently installing 3.73's into my 9 bolt (YES, it is a 9 bolt & YES they are 3.73's, not 3.70. I currently have 4.10 gear sets and new series 3 carriers in stock for 9 bolts )

Hey Killr TA--I heard you had the Koni shocks. You like those more than Bilsteins?

Also, did you check online for gears? You might try to use the search function...Google.com is a good one. If you find places, maybe you can make a thread like you made for the stealth ram, eh?

 

Here you go. www.9bolt.com More stuff is on the way too.

Lets not forget Strange Engineering. They have 3.70's and a rebuild kit that has new bearings and shims and stuff. I just had some installed in my car about 2 months ago.
Of course, the gears are like $350 and the install kit is $90
