FTI Performance billet input shafts are specially engineered for high-horsepower engines equipped with GM 4L80E/4L85E transmissions. They're constructed from hardened, aircraft-quality 300M billet steel for added strength and lubrication holes for increased flow and strength. These ultra-durable components feature a resized diameter to provide optimum stress distribution along the entire length of the shaft, and along the extended high gear splines to the oil ring. FTI Performance billet input shafts are stronger than OE, making them a necessary component for pro-street and off-road applications.
