I have an AMC 20 (narrow trac) with a 4.10's and a Powertrax lock-rite locker. I am looking to upgrade to 1 piece shafts. I do light to moderate wheeling, but I really don't feel comfortable with the original 2 piece shafts. I was looking into getting a set of superior shafts but I noticed that they are not compatible with the powertrax lock-rite. So I called superior and they said that the shafts are too short and this particular locker won't engage the shafts. Has anyone run into this problem? Are there any other shafts that will work? I would like to take the most cost effective route.

Have you tried Moser?
