I'd be impressed if it was 4140 instead of 4130 which is the weaker of the 2 grades by a good margin for that type application, 4130's wear resistance is much lower. I work with both on our production line part holding fixtures for the robots.
With some of what she was saying I have to wonder if she wasn't confused on the specs in general. OEM is not aluminum it's steel, pretty sure cast not forged with the number of breakages I'm hearing about.

I would call Cycle-Rama or Star Racing to get in line.
I bought from (emailed) TTS in UK because his was the first one I saw on the market when doing my build, it was $$$$ though for shipping etc.

In case anybody cares, I'm running a TTS tool steel comp ramp and Rekluse TorqDrive clutch.
I started with Redline primary oil but after having the primary cover off to switch clutch springs I changed to Harley Formula+, very smooth shifting, neutral easy to find and quiet primary.
Everything just seemed a bit better than with redline oil which is quite a bit thinner.
