I have a 96 xj, 4.0, aw4 automatic, and np231j t-case w/ a rubicon express hack n tap sye. Im in the process of buying a teralow 4:1 kit and was wondering if the hack n tap will hold up to the added torque that the gear reduction applies or if im best buying teraflex's short shaft kit as well? thanks

The hack n tap is not a good solution. Do you really need they "short" output? Why not get a AA HD SYE. The AA hardened shaft will handle the torque much better.

i have a 4:1 with AA SYE for sale...
