Apparently it's a micropolishing process that makes the surface of gears smoother than can be accomplished by the tools that are used to cut them - I see it advertised by some who sell differential rebuilds - does it really make an appreciable difference?
Send Gary Ramadei (GTR1999) a PM and ask him his recommendations.
We had this discussion when he built my Super 10 bolt.
He will explain it much better than I can and will steer you in the right direction for your build.
I bought a used 3.70 9 inch Ford gear Joe Gibbs Racing that had REM finish and the gear looks like chrome. They apparently use one time and then discard , I’m still using the gear in my 427 Ford Fairlane stick shift drag car (street gear) with way over 600 hp when on street with drag radials and manual transmission . No complaints
I know nothing of the REM process, but my concern would be whether the gear teeth had enough surface [micro]-roughness to retain a surface oil film. Racing folks might be fine with it since it reduces friction. But,, does it also reduce gear 'life' because of less oil film thickness? I would love to know Gary's thoughts on this issue....
These are my REM polished gears. Almost a chrome like appearance. Mike Dyer did my rear and recommended it and I believe Gary likes it as well. I also had mine Cryo ‘d as well.

The process is called mikroniting.......and it works by reducing stress risers in machined material. These stress risers can cause cracking under extreme use and cycle fatigue.......
It's great...but how much it is needed at the street level is open for debate......and it is just another added cost.
CRYOGENICS improve the metal and REM is a finish. I had a debate with the boss years ago about buying Cryogenic parts to make them last longer. Even doing disk brake rotors. So we race tested Cryo against non Cryo. Yes, they lasted 50% longer, but they cost over 50% more. So it was not cost effective for rotors. But ring an pinion, crankshafts, and billet steel cam shafts it is worth doing. https://procryo.com

Thoughts on REM finishing?
