Chevy V8 SFI Billet Flex Plate 168-Tooth Int Bal

The Chevy V8 SFI Billet Flex Plate 168-Tooth Internal Balance (model FPS094) is a precision-engineered component designed for street and performance builds running automatic transmissions behind small-block and big-block Chevrolet V8 engines. This flex plate serves as the critical connection between your engine's crankshaft and transmission, transmitting torque while accommodating engine movement. Whether you're rebuilding a stock 350, upgrading a 454, or tuning a modern crate motor, a quality billet flex plate ensures reliable power delivery and eliminates flex-related harmonics that compromise driveline integrity.

Manufactured from billet aluminum rather than cast iron, this internally balanced flex plate reduces rotational mass while maintaining superior strength and durability under high RPM and high-torque conditions. The 168-tooth count matches OEM and most aftermarket torque converters, ensuring proper engagement without slippage or premature wear. Internal balancing means the flex plate accounts for your engine's rotating assembly mass, allowing you to run a lighter, more responsive driveline without rebalancing your crankshaft separately. The precision-machined design distributes stress evenly across bolt mounting surfaces, preventing fatigue cracks that plague inferior cast alternatives. At 7.83 lbs, the weight savings contribute to reduced rotational inertia, improving throttle response and acceleration characteristics.

This flex plate is ideal for enthusiasts running TH350, TH400, 700R4, 4L60E, or other popular Chevy automatic transmissions paired with internally balanced crank assemblies. Installation requires removing the transmission and engine oil pan, then bolting the flex plate directly to your crankshaft flange using the existing fastener pattern. Verify internal balance specifications on your engine build before purchase to ensure compatibility—this unit is engineered for motors already internally balanced during machine work. Professional installation is recommended to guarantee proper torque sequence and runout verification, critical for driveline vibration elimination.
