Flexplate SBF 164 Tooth 50oz External Balance

The Flexplate SBF 164 Tooth 50oz External Balance is a precision-engineered component designed for small-block Ford engines that require external balancing in high-performance applications. This flexplate serves as the critical link between your engine's crankshaft and automatic transmission, absorbing vibration and torsional loads while maintaining the exact balance characteristics your engine demands. Whether you're building a street machine, bracket racer, or restomod, selecting the correct flexplate is non-negotiable for reliability and longevity.

The 164-tooth design of this flexplate is engineered to match the specific balancing specifications of externally balanced small-block Ford engines, particularly those using dedicated external balance harmonic dampers and flywheels. The 50oz external balance weight specification indicates the precise counterweight distribution needed to achieve zero vibration at the crankshaft, preventing harmonic imbalance that can cause bearing wear, seal leaks, and transmission damage. TCI's manufacturing process ensures concentricity and durability, with proper material composition that handles repeated combustion cycles and torque converter engagement without flex fatigue or cracks.

Mechanics and engine builders choose this flexplate when retrofitting externally balanced crate engines, rebuilding classic muscle cars with modern powerplants, or assembling competition engines where precision is paramount. Installation requires proper torque sequencing and alignment with your transmission's torque converter, making professional installation recommended for optimal results. Verify your engine's balance specification—whether internally or externally balanced—before purchase, as using an incorrectly balanced flexplate will cause severe vibration and potential catastrophic failure.
