Steel SFI Flywheel - SBC 168 Tooth - Int. Balance

The Steel SFI Flywheel - SBC 168 Tooth - Int. Balance from PRW Industries is purpose-built for small-block Chevrolet engines requiring reliable, street-legal power transmission. This internally balanced flywheel serves as a critical mechanical bridge between your engine's crankshaft and transmission, designed specifically for builders who demand SFI certification without sacrificing durability.

Engineered from high-quality steel, this flywheel minimizes vibration and harmonics across the entire RPM band, which is critical for consistent drivability and longevity in modified SBC applications. The internal balance design means the reciprocating mass of your crankshaft, pistons, and rods is accounted for within the flywheel itself, eliminating the need for separate external balance weights that can degrade over time.

At 21.45 pounds, this flywheel offers the weight-to-strength ratio serious engine builders require, providing adequate inertia for smooth engagement while remaining light enough to support higher-RPM builds. SFI certification ensures compliance with sanctioning bodies and provides legal documentation of safety standards for both street and competition use, making this flywheel an ideal choice for performance street engines.
