SBF Premium Flexplate 164 Tooth Ext. Balance

The SBF Premium Flexplate 164 Tooth Ext. Balance is a precision-engineered flexplate designed for Small Block Ford engines requiring external balancing. Built for professionals who demand reliability in high-performance and heavily modified applications, this flexplate serves as the critical connection between your crankshaft and torque converter. Whether you're running a street machine, tow rig, or race vehicle, proper flexplate selection is non-negotiable for drivetrain longevity and vibration control.

Manufactured from premium steel construction, the SBF Premium Flexplate features 164 teeth for reliable starter engagement and an 11.5-inch bolt circle designed to match Small Block Ford specifications. The external balance design means this flexplate is weighted to work with externally balanced crankshafts and matching harmonic balancers—a critical compatibility factor often overlooked during rebuilds. At 28 ounces with optimized weight distribution, this flexplate minimizes vibration transfer to the transmission while maintaining the precise balance characteristics required by your engine's rotating assembly. The tooth design ensures positive starter contact across the full engagement surface, reducing wear and startup strain over thousands of cycles.

This flexplate is essential for Small Block Ford engine builders, transmission shops, and enthusiasts performing engine swaps or rebuilds where external balance specifications are in play. Verify your engine's balance type before installation—pairing an externally balanced flexplate with an internally balanced crankshaft will cause severe vibration and potential component failure. Installation requires proper torque sequencing and use of threadlock on fasteners; professional installation is recommended for best results. Compatible with any torque converter engineered for the 11.5-inch Small Block Ford bolt pattern.
