Thank you guys.  Those was good pics. Now I understand.  What all in the motor can you have cryod' and what would you gain from it?

If you have parts that are NEW and have not experienced any usage or stress, that is the best time to finish the heat treating process with cryo treating.  Cryo treatment is not magic, but a place where a lot of uninformed guys spend a lot of money for a process that is over rated for the kid of parts we use on the LT 250 and LT 500 Suzuki and the metal the Suzukis are made of.  If you are building space shuttle parts or parts for formula one race cars where the ultimate strength and minimal weight are the prime objective then the cost of cryo treating can be justified. 

Cryo treating is not going to add life to the corners or edges of the dogs or sockets that get rounded off due to mileage or abuse.  Cryo treating is not going to add life to the surface of the gear teeth that ware due to mileage or lack of lubrication.  If you have components that others have had a history of breaking due to being used for purposes that they were not designed for, then cryo treating might be used as a last resort to nudge the strength to a very slightly higher level.   Cryo treating MIGHT add a little strength to the core of the gear and prevent a gear from splitting in half or a tooth on a gear from breaking off due to being overloaded.

I can think of many other area where my customers should first spend their money and do not recommend cryo treating their parts.
