Mine is rusty steel. Go look under a new 2014 sitting on the lot, it will look just like yours.

Red Recluse

I have my results for the factory vs. the 4' axle exchange one piece aluminum DS from American Muscle. My 2013 v6 manufactured Oct. 2012 (10/12) weighed 29 pounds, the aluminum one piece weighed ~21-22 pounds. Only being 7-8 pounds lighter I did notice a slightly smoother feel, and a sharper/direct snap when punching it at any speed.

Not to re-open a old thread or anything. Just wanted to share my results to help anyone else looking for information on this subject.
