1957-1985 Small Block Chevrolet and 1978-2014 GM 90 degree V6 - 153-Tooth - Internal Balanced
OVERVIEW
Hays heavy-duty flexplates for high-performance and competition engines are constructed of a thicker than stock steel plate, enabling them to withstand the stress of high-stall torque converters and today's high-RPM engines. While factory stock plates tend to crack around the crankshaft hub when punished under high torque and RPM conditions, the thicker Hays Flexplate handles the force. These H.D. 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. All Hays heavy-duty flexplates are zinc-dichromate plated to resist corrosion and are SFI certified under specification 29.1.
Features:
- S.F.I. 29.1 Certified
- 153 Tooth Ring Gear
- Internal Balance Chevy V6 Engines
- Zinc Dichromate Plated
- Heavy Duty
- 0.030" thicker than the stock flexplate
