In spirit the engine is an AMG but not in name. AMG is owned by Mercedes. DCX owns both Mercedes and Chrysler. AMG is in the family tree but on the other side.
Kinda like your cousin's wife is in the family but she's not related by blood.

It's a twisted little world we live in.

We sell the AMG shift ***** as well as several other non-MB ***** but I haven't had a 6 speed to try them on. When I get my SRT here, I'll find out if our ***** will fit.
