Extreme Duty Flexplate - SFI SBF 164T - Int. Bal.

The Extreme Duty Flexplate - SFI SBF 164T - Int. Bal. is a critical drivetrain component engineered for high-performance Small Block Ford builds that require superior structural integrity. Designed to bridge the gap between the engine's crankshaft and the torque converter, this flexplate provides the necessary durability for racing and heavy-duty street applications. High-horsepower engines place immense stress on standard drivetrain parts, making an SFI-certified upgrade essential for both safety and mechanical reliability. By choosing this Xtreme Duty Platinum series component, builders ensure their drivetrain can handle the increased torque loads associated with modified aftermarket cranks.

Constructed from premium steel, the Extreme Duty Flexplate - SFI SBF 164T - Int. Bal. features a 164-tooth ring gear precision-welded to meet rigorous SFI 29.1 specifications. This certification indicates the plate has undergone stringent testing to ensure it remains intact under extreme rotational speeds and high-stress environments. As an internal balance component, it is specifically designed for engines where the rotating assembly is balanced independently of the flexplate itself. The robust design minimizes the risk of cracking or warping, which are common failure points in factory-style flexplates during sustained high-RPM operation.

This Extreme Duty Flexplate - SFI SBF 164T - Int. Bal. is optimized for Small Block Ford enthusiasts utilizing aftermarket crankshafts that necessitate an internal balance configuration. Its 164-tooth count makes it compatible with standard Ford starter motor alignments used in larger bellhousing applications found in many performance builds. Whether you are finishing a track-focused restoration or building a high-torque street machine, this component offers the peace of mind required for competitive environments. Proper installation ensures consistent engagement with the starter and a vibration-free connection to your transmission system for long-term reliability.
