Description

The ATI Performance Products 915663 flexplate is engineered for high-performance and racing automatic transmissions, meeting the stringent SFI 29.1 certification. It is constructed from custom-drawn, SFI-spec chromoly steel, ensuring superior strength and reliability under demanding conditions. The flexplate is further reinforced with a double MIG/TIG welded design, providing exceptional durability. Featuring a 130-tooth ring gear and an internal engine balance, this flexplate is specifically designed for Gen 3 Hemi engines paired with NAG1, 8HP70, 8HP90, or 8HP95 transmissions. It comes complete with 10.9 spec crank bolts, simplifying the installation process. This flexplate is a direct replacement and upgrade for various Hemi applications. Important fitment notes: This flexplate is designed for 5.7L, 6.1L, 6.2L, and 6.4L Gen 3 Hemi engines. However, it does not fit the 5.7L Jeep Grand Cherokee. For installations utilizing OEM converter bolt holes, the included longer bolts are required.
