I sent an email to AAM asking about limited slip or locker upgrades. I also asked if it was possible to make the factory limited slip more aggressive. No word back yet.
I have found more than once that I was only able to get power to one wheel(most of the time after turning tight, then stopping). I had to put it in 4x4 to get moving again in wet grass. Would love it if I could swap out some springs or something to make it do what I want. I restacked the clutches and frictions in my 97 to make it work for me.
