** which means , the J shifts can easily be altered to have front drive only with a twin stick set up , however , the possibility exists of putting one in low range while the other is in high range , which will pretty much destroy it immediately.
The T-shift will not allow you to do that (front only or mixed ranges) , even with a twin stick set-up , unless you go deep inside the t case and make modifications . The benefit of the twin stick in this case is being able to go from 2x4 to 4x4 or vice versa , hi or lo , much easier than before.
