My Cat is stock power and an A8 with a D.I.R.S differential brace. I track it at the drag strip often and sometime in the near future I'd like to up the power to around 725-750 plus WHP.

I was looking into upgrading the axles for preventative maintenance if it's absolutely necessary at that power level or are the stock Hellcat axles fine and hold up well?

For what it's worth it's a 2019 so I'm not sure if the axles have been beefed as opposed to the older models?

I have a 2015 and broke an OEM axle because I broke the Diff Box. You are correct the 2019 are beefed up compared to the very early years.
With the Diff Brace you shouldn't have a problem. I call the P4Developement Diff Brace "The Best Peace of Mind Part" I have installed!
My Husband @Top Cat like to build for safety and strength too.

Get the OEM Widebody 41-spline axles.

Ok sounds good. If I don't have to spend the extra coin to upgrade the axles then that works for me. The only other thing I'd upgrade is the driveshaft and I guess I should be good to go.

Since my Cat is a 2019 with the beefier axles and I have a D.I.R.S differential brace I guess I can make do without getting some axles.

Interesting I'll keep that in mind. I had thoughts about upgrading to the Redeye axles but I can't find where to purchase them. 🤔
