Can someone explain the advantages of having on of these? How different would this preform over a normal posi?
Thanks for any insight you can provide.

Re: Auburn Racing Differential
This is new to me. There are no pictures of it, so I don't know if it's a modified version of there Auburn and Auburn Pro LSDs, or if it's something completely different. It must be pretty tight if they won't allow it's use on the street.

Re: Auburn Racing Differential
Seems a little involed just to get a locker or posi.
I have a powertrax locker in my 89. It's a 7 5/8's 26 spline. That works great. It is very streetable, works great on a track too.
I will say this though. At low speeds turning (in and out of parking spots for example) it does snap and pop some times, and you will feel it when it engages at low speed.

Re: Auburn Racing Differential
I have one, and when i called Nancy, she kept trying to get me to send it in and trade it out for a "Pro street" version. I couldn't get anything out of her, much like a politicion, she evaded my question. She did say that it cost $800, so there was no way i wanted to give it up. All I got from the previous owner was an installation manual.
I hope someone here has some knowledge.

Re: Auburn Racing Differential
Apologies for the double post, but i did fid some information.
In the road race series Auburn Gear has developed a performance limited slip differential specifically for road racing - a differential case designed to allow the center pin to float along with the axle shafts. This design feature aids the driver when cornering, so that when the driver is turning, the outside wheel axle shaft will apply a force to the center pin hence, the pinion gears will firmly seat the inside cone/side gear assembly giving the racer an extremely tight rear axle. The greater the G-force the more bite you get! If you are an avid road racer you'll want this unit. It'll allow you to pass your competition!
I am not sure exactly how this makes it any better than a regular POSI, but there you have it.
