A dry deep freezing process using flashed liquid nitrogen (LN2) freezing metal parts to 300 Below for 72 hours to modify molecular structure. The metal brake rotors, bearings, axles, etc are then brought back up to room temperature resulting in substantial improvement in wear resistance. Used the U.S Government on military vehicles and rifle barrels. Also used by major race car companies for improved reliability.


There used to be a military secret about a process of tempering metal to improve its strength/longevity used on rifle and other weapon barrels, tank tracks, aircraft propellers, wheel bearings, etc. This metallurgical process changes the molecular structure of the idioms configuration. This process freezes metal parts to 300 below zero then slowly brings it back to room temperature in scheduled stages while submerged in liquid nitrogen which dramatically improves the longevity of the metal. The tempered metal has been shown to be substantially harder and thereby last substantially longer than regular metal. After the cold war the process went public and is now used on race car engine/suspension parts, commercial aircraft production, police cars, emergency vehicles, ambulances, etc.  In 2007 we were restoring a B4V-TDI for an aeronautical engineer for Boeing when he introduced us to this process. Since then we have included the process to many of our B4V-TDI customers. We temper the brake rotors, wheel bearings and races, ball joints, strut mounts, striker studs, bushings ad other parts. This adds to their longevity and gives our B4V-TDI owners less maintenance cost and therefore more peace of mind.
