Im in the metro DC area and hoping any of you know of a place that does cryo treatments for parts and such...im planning on building a diff and wanted to give the case and gears more strength and durability!!!

Yeah, there are a couple places around. How local are you looking for? Do you know what test procedure you want done to the part or are you expecting the place to have experience with this sort of thing specifically?

Hmmm...YEah...No Idea man...I would love to have someone who knows how to treat gears and casing and such...But I just dont want to ship the parts to someone else :-/

So any info is good info...I live in Manassas area and dont mind a little longer drive ~ 50miles

There are many Industrial metal conditioning type facilities around, but all of them will be asking you specifically what (I mean milspec or custom) process you want done for your part and will probably charge you much more then you are willing to pay.

I had not heard of people using this for automobiles yet and did a bit of poking around. It sounds like there are a couple of shops that have been set up purposefully for the automotive enthusiast and it seems this is what you are more looking for.

I am sorry, I don't know of any of these specialty automotive shops in this area. Why are you against shipping? is it the cost? some of the places have this factored into their pricing structure.

I saw these in this region, not within 50 miles. But shipping should be fast.

To build on what Toroids said,

Cryo is still a mixed bag. It can work, but there are no guarantees.

Industry is studying cryo openly to better understand what it does from an engineering point of view. Sometimes it helps, sometimes it doesn't. It usually takes process development and good process control to see it consistently improve the material properties. Unlike heat treating, there really isn't a recipe book that they follow that will give good results for all of the things they promise they can do. Slowly but surely I expect that information will migrate to the public domain and then we can all find benefit from it.

Military and racing industries use cryo. They do it with performance data before/after cryo treatment and are able to tell whether a particular process is helping and then they pin down that exact process. So most of the good processes are confidential to those customers.

There are many new cryo treatment vendors out there who don't have significant background working with military or racing customers. They just bought the chiller machine, chill anything you're willing to pay them to chill, and take in money. My gut feel is that the more they claim they can do the less real knowledge they have.

Personally I'd try to find a shop that does work with bigger customers and who have worked with those customers firsthand to develop verified processes that work.

Please don't take this the wrong way but don't bother cryo treating them, you will waste your money. Get the PFS diff brace and get a KAAZ or T2 diff. There are a few threads on it. The PFS diff brace is probably the most important piece in that puzzle.

I have a brace but its not PFS, I will be using a T2 diff, but the gears is my main concern...at the drag strip...there was a failure reported from 4.44 gears...and i dont want that to happen to me!!!
