Also the CAD axle housing is stronger too as it is made of cast and not thin welded metal on the housing, like what I have, not that it has given me any problems.
Also when changing a CAD to a non CAD, you will need the shaft seal for in the diff. housing, means pulling the diff. out but thats no biggy.
For me it costed me about $1300 to put mine under my truck and I got my coils, gears, and axle for free. What costed the most was I decided to run longarms but didnt build them myself. Other then that running stock steering linkage, trackbar, CV axles.
Good part about running longarms, you can make them work on a D44, D60, etc...
