Is there a good limited slip differential that I can swap in to my 92 Camaro RS w/ 305 and put a 3.73 gear ratio on as a direct fit? Right now it has the stock 2.73 gears and open carrier. Thanks

If you can find a used Torsen from a '98 to '02 it will work. Yukon makes a clutch type differential called the Dura Grip that is on the lower end of the price range. The Eaton Posi is a good one, but a little more expensive. Just don't use the Auburn or Eaton Governor Lock. Just be sure that you get a 3 series.

I'm assuming that you know that when you change gears you will have to set the pinion depth, bearing preload and backlash.

I am in the process of getting a rebuild Auburn, why do you say not to get one?

Auburn Gear (AG)
This is directly from Randys Ring and Pinion =

The Auburn Gear limited slip uses a cone style clutch that wears directly against the carrier case and provides the friction force to make the unit work. "This design is not rebuildable". Once the cone clutch or case wears out, the "entire unit" must be replaced. Even with this shortcoming, this design works well for occasional use where extra traction is needed. They have good impact strength in passenger cars and trucks up to 1 ton. They will hold up well to high horse power, but will not last long if there is a lot of tire spinning.

Here’s a link to his site explaining L.S.D.and Locker Carriers /Differentials = http://www.ringpinion.com/TechnicalH...ini-Spools.inc

Auburn is the worst differential I have delt with in the 32 years that I have been building rear ends. They wear out quickly if you do burnouts, can not be rebuilt (shouldn't be rebuilt) and they fill the rear end with powdered metal as they wear, which runs through all of the bearings and gears, ruining them in the process.

I'm pretty sure I have an Auburn unit but how can I tell?

5 coil springs in the center.

The Auburn is all right for a car that doesn't get abused. Many Auburn differentials have lasted for many years with no problems. If you like to do burnouts then the Auburn is definitely not for you. It would be my last choice for a limited slip differential.

Jake, unless you plan on doing a cam swap, the stock rpm power band is too low for the 3.73 gearing and works best with 3.42 according to what I have read. After reading this thread I put a hold on getting the auburn and now looking at either a torsen or eaton posi(not gov lok)and 3.42 gears.

Take a look at the Yukon Dura Grip too. It's a little cheaper than the Eaton Posi, and other than the clutch material it's the same thing.

I actually plan on doing a complete engine swap; A gen I 350 sbc.
