arb dana 80
I pull with a dana 70 arb locker, works great much beter then a detroit with the obvious disengage ability. It engages every time works like a charm very strong im pushing 750 horse power with a stage 6 ats transmission. I snapped the crown and pinnion and the locker is fine. I especially like how the parts inside slide in and out of position quickly and its built very strong. i swapped my 70 with a 80 and disc breakes so right now i just have posi, let us know how it works out im in the prosses of selling my 70 locker for a 80.
