Select this item to add cryo treatment to any connecting rod set (includes bolts) that you are purchasing. This may add up to one week to delivery time but generally we keep pre-treated parts in stock so there is no difference in delivery time.
Whether a metal performance part is cast, forged, welded, formed, bent, whatever; the process used to make the part introduced internal and external stresses. Cryogenic tempering freezes these parts to hundreds of degrees below zero then slowly and with precise control bring the parts back up to room temperature. This process allows the metal grain structure, especially in these high stress areas, to realign itself. The first obvious benefit is reduction in these stresses which reduces premature parts failure and extends part life. Second, in some cases this process can reduce friction and heat which also results in longer part life as well as lower heat and more power.
