    Drive lines



    I have a burning question rolling across my mind. This may be elementary to the hard core but to me a newbe to wheeleen and I am ready to order my driveshafts I have a question.

    Can anyone tell me why the Jeep manufacturers use such a small diameter driveshaft? Does it have some added value in using such a small diameter, especially for the front which has a sizable length to it?

    It was mainly for clearance on the auto trans equipped vehicles. They only made 1 "flavor" for cost savings (this is AMC we're talking about). Once you lift them it's not a problem anymore. I had a couple of front shafts built from the stock OD, .188" wall tube (I think factory is .120"), and I promptly twisted them out of phase. The front shaft in my Jeep now is 2" diameter .188" wall. I haven't twisted it in about 5 years of 'wheeling.
