All KJ's w/ the 8.25 run 29 splines in the rear and 27 in the front, maybe that's the problem. 95% of KJ's have the 8.25... a couple have the M35 w/ a bolt in axle and that one DOES have 27 splines. Old school funky... Just ask Ferg! Anyway, we make a locker for both now.

To my knowledge, Auburn hasn't done an ECTED for the 8.25. They make a posi, Eaton/Trac Tec does the Detroit or the TruTrac and we make ours. The No Slip is what it is, it's a drop in.
