ATI Performance Products, Inc®, is proud to introduce an all-new Vasco Input Shaft (part #704000) for the 8L90E 8-Speed transmission. 100% designed, made, heat-treated and ground in-house at ATI, this Input Shaft features a tighter spline fit to the OEM forward drum. It's made from heavy duty American-made Vasco Max Aerospace Steel, so it's exceptionally strong and resilient and able to withstand the abuse of high horsepower use. The shaft acts like a torsional spring bar, twisting and returning to totally eliminate breakage while reducing shock loads to the gear train.

ATI Performance Products is located in Baltimore, MD, and specializes in producing and maintaining high performance products for street and strip applications. Over the years ATI has earned a reputation for its cutting- edge technology, attention to detail, and rigorous testing under race conditions.
