SBC Flexplate - SFI- 168 Tooth- Int. Balance

The SCAT ENTERPRISES SBC Flexplate - SFI-168 Tooth - Internal Balance is purpose-built for small-block Chevrolet engines where you're running an automatic transmission paired with a high-performance crankshaft. This component bridges your engine's crankshaft to the torque converter, and it's engineered to handle the demands of modified powerplants where stock flexplates fall short. Whether you're building a street machine, a weekend racer, or restoring a classic with modern internals, a quality flexplate rated for SFI certification ensures reliability under sustained boost, nitrous, or high-RPM operation.

This flexplate features 168 teeth and is internally balanced to match an internally balanced crankshaft—critical for vibration control and bearing longevity in high-output engines. The SFI-168 rating confirms it meets sanctioning-body standards for drag racing and performance competition, meaning it's been stress-tested to handle sudden load reversals and extreme torque multiplication through the converter. Cast ductile iron construction provides the strength needed to transmit peak horsepower without flex or failure, while the internal balancing eliminates the need for external weights that can shift or loosen over time.

This flexplate is ideal for SBC engine swaps, restorations, and any small-block Chevrolet automatic build where you're matching an internally balanced crank. Verify your crankshaft is internally balanced before purchase—pairing an internally balanced flexplate with an externally balanced crank, or vice versa, will cause destructive vibration. Installation requires basic engine-out service; the 14.5-inch diameter fits standard small-block bell housing patterns. Weighing 6.9 pounds, it's a direct bolt-on for most SBC automatic applications running 168-tooth converters.
