ATI Performance Products, Inc is proud to offer 139-Tooth, 10 DP, SFI Flexplate Kits for GM LS, LT and Vortec engines. These kits include an SFI 29.1 Flexplate, a precision-machined crank adapter and ARP bolts. ATI’s 6-bolt kit #915578 fits popular GM LS1, 2, 3, 6, 7 & L98 racing applications, and our 8 Bolt kit #915579 fits GM LT1, LT4, ZL1 Z-Body, CTS-V with LSA & LSX. These kits require an aftermarket 10DP starter and only work with aftermarket style converters. No LS length pilot or adapter is needed for the converter, but a 10 DP pinion starter is required.
A high-performance flexplate is a critical component between today's engines and expensive transmissions. Manufactured in house on state-of-the-art CNC equipment, most of ATI’s flexplates are double MIG and TIG welded with inhouse robotic welders. Each flexplate is made with certified American-made materials that far exceed SFI specs for safety. ATI flexplates are manufactured and toleranced from actual OEM drawings to ensure accuracy. Each flexplate is quality inspected and exceeds OEM flatness and run-out tolerances before being precision balanced with a resolution of 1/10 oz. Choose a genuine, American-made, quality flexplate from ATI!
