Thanks. I did a bit more research as you were posting. It seems the 19 and up even including the regular hellcat got beefier axles. The drivers side one is 53010849AB. It retails for 950 give or take and is sold whole sale at 603-675. I have the DSS race axles with their upgraded road race axles. The drivers side one is banging like a tin can now at speeds lower than 50. I had an extra DSS axle sitting in the garage. DSS got it 3.5 weeks ago. I asked what is happening with it as it is dangerous to drive my car. DSS responded by saying their "return specialist" is no longer with the company and they are way behind. So I will probably go with Rock Auto even though they are a little more expensive vs. other wholesalers. I just trust them.
