Flexplate 168T 400 SFI External Balance

The Flexplate 168T 400 SFI External Balance from ALLSTAR PERFORMANCE is a precision-engineered component designed for small block Chevy engines requiring external balancing. This 168-tooth flexplate serves as the critical interface between your engine's crankshaft and automatic transmission torque converter, handling rotational forces while maintaining perfect harmonic balance. Built for builders and mechanics who demand OEM-quality reliability in high-performance and modified applications, this flexplate meets SFI 29.1 safety standards for sanctioned racing and street performance builds.

Manufactured from durable steel, the Flexplate 168T 400 SFI External Balance features a two-piece seal design that accommodates the specific balancing requirements of externally balanced crankshafts common in small block Chevy applications. External balance flexplates require precisely weighted counterweights positioned opposite the internal engine imbalance, which this component delivers through precision manufacturing tolerances. The 168-tooth count ensures reliable starter engagement across all standard small block Chevy configurations, while the SFI 29.1 certification confirms this flexplate has undergone rigorous dynamic testing and meets sanctioning body requirements for breakage containment.

This flexplate is essential for engine builders working with externally balanced small block Chevy strokers, race combinations, and modified performance builds where stock internal balancing won't suffice. Mechanics installing this component should verify crankshaft balance specifications before purchasing—external balance flexplates are not interchangeable with internal balance units. Weighing 7.19 lbs and compact in design, the Flexplate 168T 400 SFI External Balance integrates seamlessly into transmission bellhousings and delivers the vibration control and safety certification required for dependable operation at elevated RPMs.
