I found a d44 to swap into my 2001 cherokee but I was curious if there was really a point in it. My 8.25 is 29 spline, the d44 is 30 spline, other than that I dont really know much of a difference, maybe being able to gear the d44 higher but im only going to run 33's so not much use there really. Can anyone tell me any advantages?
