If anyone can help out that would be awesome. I have 4.11 gears in my garage that I want to put in, but I don't want to without some sort of traction control. Are drum axle, 3-series, LSD units hard to come by? I've been looking around for a long time and noone seems to have any for sale. If I can't find one soon I'll have to buy new. Any suggestion or offers?

For the posi unit drum or disc doesn't matter if that helps your search. Spline count on the axles matters though, if you have an 89 you could have 26 or 28 spline axles I believe.

So it turns out I need a 26 spline, 3-series LSD carrier.

I like your explanation better though.

Ahh didn't realize LSD was an acronym for Limited Slip.

Limited Slip is a GM term Wink

Posi-tractrion is just a "GMism" for a clutch type Limited Slip Differential or LSD. there are three types of LSD; clutch, viscous and helical.

You do know that I could post on Wikipedia that the sky is red... and it'd be there.... It's not credited information

I know. But then again most everything on the internet isn't.

my brother uses "limited slip" when talking about toyotas, BMWs and Nissans... i had always figured it was the "official" term.

I always kind of figured that "limited slip" was just a generic term for anything that will have two wheels turning on any manufacturers car.

I always thought each manufacture had there own cute little name for it (IE, chevy: Positraction, Ford: Equa-lock, Mopar: Sure-grip.)

oh well. Rolling Eyes

Dang........when I saw the "LSD" thing I thougth I was having flashbacks to the 60's Wink

LSD was the term for "Lysergic acid diethylamide" One of those "mind altering drugs we had back then.

Now that we all are on the same page...

Back to my post. Like I said before, I'm looking for some kind of traction control. The rear end in my car is a GM 10bolt that will accept 26 spline 3 series carriers. If anyone has anything that will fit back there I would greatly appreciate it if it was for sale. What I don't want is a 2 series commonly found on IROC's or other V8 cars.

2 series carrier is fine if you use a ring gear spacer. There about $40 - $50 . If you got a smoking deal on a two series it would be worth it.

I'm slowly learning about camaro axles...

A stock GM 10 bolt camaro axle is a 7.5" right, not 7 5/8"? I have a 2 series LSD at home, but I hadn't known it would work until I just found out the spline count are the same. I'm going to track down a spacer and get it.
