Not sure where to really put this, so here it is. I came across a place that does cryo treating out by Palmdale while searching for a cure to my WJ's never ending warped rotors.
Shot them an email for a quote on a pair for rotors, a Dana 20 output shaft, and a pair of rear axle shafts. We'll see where it goes.

sounds interesting. Let us know. I'm sure you could have found a place closer, Palmdale is a long way to go to get a cold shaft.

You'd think so, but for some reason I'm having trouble finding places to do this.

The quote I got back was $50 for the pair of rotors and $3.50 a pound for the shafts. I tried that guy on the Pirate board that started a cryo business and he was $45 each on the rotors, $20 for the D20 shaft, and $60 each for the axle shafts. He's also in Nor Cal.

doesnt sound too bad. What kind of strength increases are we looking at?

20% or so
