SFI Flexplate Chevy V8 168 Tooth Int Balance

The SFI Flexplate Chevy V8 168 Tooth Int Balance is a precision-engineered flexplate designed for small-block Chevrolet engines requiring a 168-tooth configuration with internal balance. This component serves as the critical interface between your engine's crankshaft and automatic transmission, transferring torque while maintaining rotational harmony in high-performance and modified applications. Built to SFI 29.1 safety certification standards, this flexplate ensures reliable power delivery in street, strip, and racing environments where component integrity is non-negotiable.

Constructed from high-grade steel, the SFI Flexplate features a two-piece seal design that accommodates internal balance rotating assemblies, eliminating the need for external counterweights on your crankshaft. The 168-tooth configuration is specifically matched to small-block Chevy applications and ensures proper engagement with your starter motor for reliable cold starts and repeated cranking cycles. Internal balance design reduces overall assembly weight and simplifies engine bay layout, while the SFI certification guarantees this component meets rigorous safety standards for containment and structural integrity—critical when operating at elevated RPM or boost levels.

This flexplate is ideal for engine builders, performance shops, and enthusiasts upgrading to internally balanced stroker kits, crate motors, or custom rotating assemblies in Chevy V8 platforms. Whether you're installing a 383, 408, or internally balanced small-block in a street rod, muscle car, or racing application, proper flexplate selection is fundamental to transmission longevity and driveline stability. Installation requires careful alignment with your torque converter and proper fastener torque specifications; verify compatibility with your specific transmission bellhousing before ordering.
