SFI 29.1 Approved Flexplate (GM LS9 Engine)

This new series of flexplates is designed to prevent cracking and ring breakage in high performance GM LS9 9-bolt crank applications. These flexplates are SFI 29.1-approved and made from premium A36 steel plate material, which is much stronger than the factory originals. They also feature a heavy-duty ring gear for added strength. Each flexplate is electro-coated to eliminate damaging elements and vibrations and is also dynamically balanced with factory bolt sizes.
