I think that is the reason right there to use a Aluminum when you are allowed.

I put a M/W 3" aluminum in mine. Very happy with it.

M/W doesn't make a 3' aluminum shaft only 3.5

Another vote for M/W....only took them a few days from ordering my aluminum shaft to arrival; great technical support when ordering and absolutely no problems.

We run 3” aluminum in all my cars and Fleetpride does them all. They do a great job, and they are local (nationwide)! If something goes wrong, we just drive over and they take care of it vs sending it back and talking to a guy on the phone.

Your are absolutely right. It is a 3.5". Sorry my mistake.
