Performance Cryogenics

[Bulldog]

Hey guys,
I was wondering if any of you guys use any of the Cryo company's out there to increase the strength of your gears and things.
The reason that I was wondering is I just sent some gears out of my NV 5600transmission out of my Dodge 3500 dually down to Performance Cryogenics in Mooresville N.C. I have taken out 6th gear a few times and don't see it stopping unless I can get some stronger parts. (Big power + heavy loads = breakage). After talking with Lyle down there I felt pretty comfortable send him the parts.
So how about it any of you motor sports guys sending your parts out to be treated? Did it help?
See ya,

There was one guy that did all the lower units. He made them bullet proof. No one ever asked how.

Rumor was everything was frozen.

Here is another process that might help make your gears last longer, at least reduce wear on them and maybe get you some "slightly" better mileage.

I have no personal experience with it but it is suppose to be the cat a$$ for gears.

Also look into meta-lax. It's a stress reliever.

I used to be a rep for 300 Below and we did a ton of stuff for a bunch of the big name racers. It worked good on many things. Mainly on things with .4 or higher carbon (like 1040,4140 etc...) but worked super on stuff like 1090.
Worked a lot of good on tool on tool steels. You may see some improvement. Hope that sounds encouraging for you. It's been about 10 yrs ago now.

Thanks guys,
I had the parts overnighted to Performance Cryogenics they did there deal and overnighted the parts back so hopfully I get the transmision back together today or tomorrow and should have the truck back together and on the road Monday.
I'll report back on how the gears hold up.
see ya,

Well, you cant do it now, but I Had my gears out of my T-56 tremec 6 speed in my Camaro race car Mikronited. And it has held up wonderfully to 550 RWHP and 6200 RPM clutch drops on slicks. Before that the gears would last a year or so.... If It happens again, look into it.

I'll take a look at that Bad. My problem is my truck is HEAVY and I haul HEAVY loads with the torque that my truck makes it's not hard to see why I take the teeth off the gears. The NV5600 is a very strong trans but when the torque gets over 1200 ftlbs over drive just can't take it. I'm hoping that this cyro deal works out. I just installed a DD clutch and it wont slip like the South Bend fe was. I should find out pretty soon if the new gears will hold up or not.
See ya,

I understand "cryo," but I think it is a joke. Heat treating is a much better solution to a broken gear problem. I worked for a Subaru Race Shop that is the soul importer of PPG gears from Aussy. Look them up. They are the strongest gears period. We tested all other manufactures in real race cars and they all broke. Only PPG held up to the test. "Cryo" failed just as fast as a stock gear did. I'm sure for other applications "cryo" works great, but not in a manual transmission. This was my bread and butter for many years, so trust me when I say it is all in the metallurgy and heat treating. They make gears for a wide variety of applications. Very expensive, but if you make the power and it holds for run after run after run etc.... then it is worth it.

Thanks for the reply Boostin,
I don't know if it's a joke or not the way I see it it was worth a try. I know the heat treated gears that I had wasn't going to hold up so I thought that I would give it a try. I know a lot of people use cryo so what the heck. The real solution is to back the power down or stay in direct. I wonder if PPG would even make a gear for a NV5600. I should reach out to them. Do you have a link? It would be interesting to see how they would hold up to some big torque loads. Not that your Subaru didn't test the gears but to say a Subaru has torque well now there's a joke...
