168 Tooth SFI Flexplate Int. Balance

The 168 Tooth SFI Flexplate Int. Balance from Pioneer is a precision-engineered component designed for high-performance Chevy V8 engine builds requiring OEM-spec torque converter compatibility and dynamic balance. This internal balance flexplate serves as the critical link between your engine's crankshaft and automatic transmission, absorbing shock loads while maintaining rotational harmony. Whether you're restoring a classic muscle car, upgrading a street performance engine, or building a reliable daily driver, a quality flexplate is non-negotiable for smooth, vibration-free operation.

Manufactured from heavy-duty steel, this flexplate features 168 teeth for reliable starter engagement and internal weight distribution to eliminate vibration at the crankshaft. The SFI 29.1 certification ensures it meets stringent safety standards for high-RPM applications, critical for engines operating at sustained elevated speeds. The one-piece design with integrated seal interface simplifies installation while maintaining a compact 14.7-inch diameter footprint and minimal 1.1-inch thickness, making it an ideal retrofit solution. Internal balancing means this component accounts for engine assembly imbalances without requiring external counterweights, delivering superior smoothness across the entire RPM band.

This flexplate is purpose-built for small-block and big-block Chevy V8 applications using automatic transmissions with standard torque converter bolt patterns. Installation requires engine removal and transmission separation, making it ideal for comprehensive engine rebuilds, transmission swaps, or performance upgrades where component replacement is already planned. The 6.7-pound weight provides adequate rotational inertia while remaining light enough for responsive engine characteristics. Pioneer's reputation for OEM-quality manufacturing ensures this flexplate will deliver years of reliable service in street, strip, or marine applications.
