Hello:
I was just reading, "Super Chevy", April 2007, and saw an ad for the Auburn Gear, "ECTED", Differential.
It's limited slip AND a Locker. It can be programed to come on or switched from inside the car back and forth between L-S and Locker.
Here is the link:

I am having a rear end built and was wondering if anyone has any opinions one way or the other on this product.
I look forward to hearing from you.
Thanks,
Ty O'Neal
