SFI-Certified Flexplates for Racing
Hay's heavy-duty Flexplates are constructed from thicker-than-stock grade 80 steel and engineered to withstand the force of high-stall torque converters and high-RPM performance and competition engines. This zinc-dichromate plated 29.1 or 29.3 SFI-certified flexplates are supplied with a ring gear that is securely welded in place and feature dual bolt patterns for flexibility in adapting to multiple transmission-style torque converters.
