SBC Cast Steel Flywheel 168 Tooth Int. Balance

The SBC Cast Steel Flywheel 168 Tooth Int. Balance is a critical component for enthusiasts rebuilding or maintaining classic Small Block Chevy engines utilizing a 2-piece rear main seal. This flywheel serves as the essential link between the engine and the transmission, providing the necessary inertia to maintain a smooth idle and consistent power delivery. Designed for internally balanced rotating assemblies, it ensures that the crankshaft remains vibration-free during operation. Mechanics often choose this specific configuration when seeking a reliable replacement for stock units in street or mild performance builds.

Constructed from durable cast steel, this unit weighs approximately 28.79 pounds to offer the structural integrity required for high-torque applications. The 168-tooth ring gear provides a larger diameter surface area, which is compatible with staggered-bolt starter motors commonly found on larger displacement Small Block engines. Precision machining on the friction surface allows for optimal clutch engagement and heat dissipation during gear changes. Because it is an internally balanced component, it does not feature an offset counterweight, making it suitable for standard 262 through 400 cubic inch engines that are neutral balanced.

This flywheel is specifically engineered for 1955-1985 Small Block Chevy V8 engines that utilize the traditional two-piece rear main seal crankshaft design. Builders should verify their starter motor bolt pattern and bellhousing clearance, as the 168-tooth diameter is larger than the 153-tooth alternative. It is an ideal choice for those performing a manual transmission swap or replacing a worn factory plate in a daily driver or restoration project. Proper installation requires following factory torque specifications to ensure the SBC Cast Steel Flywheel 168 Tooth Int. Balance performs reliably under various driving conditions.
