Cryo Treating

The cryo treatment process uses sub-zero temperatures down to -300º F to modify and promote a more uniform micro-structure of the material.  Benefits include:  Longer life due to reduced wear, less failures due to cracking of stress lines, and a reduced coefficient of friction on polished metals.

The following components are commonly cryo treated:

Camshaft:  Increases wear resistance of the cam lobes and reduces the tendency of camshaft breakage.

Connecting Rods:  As with all treated parts, increases fatigue life and equalizes hardness.

Crankshaft:  Reduces wear on journals, and stabilizes the crankshaft to prevent distortion and breakage due to heat and vibration.

Cylinder Head:  Strengthens the head and reduces wear on valve seats and guides, and helps prevent warping of the head due to heat and vibration.  Heads become more resistant to detonation.

Engine Block:  Reduces cylinder wear and distortion caused by vibration and heat, stabilizes the block, and equalizes material hardness.  This makes better machined surfaces.  Ideally, treatment should be done before final machining.

Valve Springs:  Greatly increases the spring life and reduces the loss of spring pressure.  Racing customers report over seven-times the life.

Rocker Arms:  Reduces breakage, flex, and wear.

Ring and Pinion Gears:  Reduces wear and tooth breakage, greatly increases life.

Brake Rotors and Drums:  Equalized hardness prevents distortion and wear, and helps prevent cracking.
