SBF Premium Flexplate 164 Tooth Int. Balance

The TCI SBF Premium Flexplate 164 Tooth Internal Balance is engineered for Small Block Ford engines that demand precision and durability in high-performance applications. This flexplate serves as the critical mechanical bridge between your engine's crankshaft and automatic transmission torque converter, absorbing shock loads while maintaining perfect rotational balance. Whether you're building a street machine, drag racer, or restoration project, an internally balanced flexplate ensures smooth power delivery and eliminates vibration that can damage transmission seals and bearings over time.

Internal balance design means the counterweights are cast or machined directly into the flexplate itself, rather than relying on external weights—this delivers superior harmonics and is essential when pairing a stroker crankshaft or high-displacement engine with your transmission. The 164-tooth ring gear provides reliable starter engagement across a broad RPM range, critical for consistent cold cranking and reliable restarts in modified engines. TCI's premium construction uses quality ductile iron and precision machining to ensure the flexplate maintains its structural integrity under continuous high-load conditions, resisting cracking and fatigue that plague inferior aftermarket alternatives.

This flexplate is ideal for Small Block Ford owners upgrading to internally balanced rotating assemblies, including those running 347, 363, 427, and other stroker configurations. It bolts directly to your crankshaft flange and mates seamlessly with any standard SBF automatic transmission torque converter. Installation requires engine removal to access the crankshaft flange, so plan this upgrade as part of a larger engine build, rebuild, or transmission service. Proper installation torque and careful assembly alignment ensure years of trouble-free operation and maximum power transmission efficiency from your Ford engine to the driveline.
