OK now I have a question. When it said in the other thread you can cryo treat any kind of metal does that include brass? Specifically what I'm wondering is if I had my tranny and rearend cryo treated would they cryo treat my syncros? If they did this to my syncros how would it affect them? If I understand the workings of a tranny correctly the syncros are supposed to cussion the gears and make them mesh correctly by matching the rpms. I believe this is why they are made of brass(soft medal = cussion). Correct? Please let me know if I'm wrong. I would like to learn as much as I can about cryo treating most of my driveline. Thanks.

HHmmmm...now i have to save up a lil more. Never heard of Cryo treating before, what exactly does it do what's done to the parts? thanks

Cryo treatment is not really "new" technology, but it has been taken several steps farther then it was 50 years ago. People used to let axles rest in dry ice for a period of time to strengthen them to a certain extent. There wasn't an abundance of aftermarket support so people used this instead.



Deep cryo is usually what you see now and is probably a lot more effective, as the temperatures are far more extreme, resulting in a better bond of the molecules. I believe parts are taken to 250-300 degrees below 0 and then slowly brought back up to normal temperature. This, in turn, literally tightens and strengthens the bonds of the molecules of the material.



Check out One Cryo for some more information.



As for the brass synchros I couldn't say for sure. The process, from what I understand of it, doesn't necessarily make parts "harder" per say, but makes them stronger.



When my time comes, whether it be rotor, piston or any other item, I'll definately be giving this stuff a try.



Good luck.
