Description

Under high shock loads the 5R55 input shaft is a weak link when you start throwing aftermarket upgrades at the engine. The factory shaft has been known to break in two or in some cases, twist the splines completely off.  This typically occurs when then transmission is exposed to hard launches or wheel hop. Throw in the aftermarket turbo or supercharger and it is not a matter of if it will break but when. This billet steel input shaft is made from heavy duty 300M material that is heat treated and stress relieved. 300M is a low alloy, vacuum melted, steel of very high strength. Essentially it is a modified AISI 4340 steel with Silicon, Vandium and slightly greater Carbon and Molybdenum content than 4340. This 300M Billet steel material is an excellent combination of strength (280 to 305 ksi). toughness, fatigue strength, and great ductility. This shaft wont break and give you the confidence to finally tame that pesky Bowtie that has been running around town. This shaft also has increased lubrication flow through resizing of the bore diameter. Some machining may be required to the stator support.
