How high are you planning on going? If you are planning on 4" or more then your drive shaft will probably fail eventually. I do not think it will break off pre sey but will give you vibrations indicating that the joint on the Xfer case is shot. some one correct me if I am wrong. Once it goes change it to a double carden shaft.

If you don't have time to do it right the first time, how do you have time to do it over.
