Years ago, when "Pro Gear" sets were becoming no longer available for certain applications, I started researching metal treatments to prolong gear life in my mopar. My search led me to Cryo and Rem finishing, or a combo of both. It didn't take long to realize, like a lot of stuff, that who was doing it and how it was being done mattered. I bought my own equipment so that I could control the processes in my shop. I'm not sure I saw any real E.T. improvement, but …( I did like thinking that I did )... . What I did see, and a testament to the treatment was triple the gear life in my 8 3/4 mopar gears. I went from breaking ring and pinions at around 40 runs, to taking them out, (for no real reason}, selling them used at 120. I'd say this is also why someone who sells gears, or doesn't do the process in house might not recommend it... just sayin ! Also, I think you'd look pretty hard to find a Pro Stock team, or a Nascar team that doesn't do every one of their rears.( check with Tommy Lee ) - Good enough for me.
