Aluminum Flywheel SB/BB Chevy 168-Tooth 2pc R/M

The McLeod Aluminum Flywheel SB/BB Chevy 168-Tooth 2pc R/M (SKU: MCL560130) is a high-performance engine component engineered for small-block and big-block Chevrolet V8 applications requiring both internal and external balance capability. This dual-purpose flywheel serves as the critical interface between the engine's crankshaft and transmission, managing rotational inertia while maintaining precise timing synchronization. Built for operators and enthusiasts who demand reliability in high-stress environments—from emergency response vehicles to competition applications—this aluminum construction delivers weight savings without compromising durability or function.

The 168-tooth design accommodates modern starter motors and ignition systems while the two-piece seal configuration prevents fluid leakage and protects internal engine components from contamination. Aluminum construction reduces overall rotational mass, improving throttle response and fuel efficiency compared to cast-iron alternatives—a measurable advantage in both street and tactical vehicle applications. SFI 1.1 certification ensures this flywheel meets stringent safety standards for high-RPM operation, critical for vehicles subjected to sustained acceleration and emergency maneuvers. The external/internal balance capability allows technicians to match the flywheel precisely to engine and drivetrain specifications, eliminating vibration that could compromise component longevity or vehicle control.

Installation requires professional engine work and precise torque specifications to the crankshaft. This flywheel is compatible with SB (small-block) and BB (big-block) Chevrolet V8 engines across multiple generations, making it suitable for both original equipment replacement and performance rebuilds. At 15.65 lbs, the aluminum construction provides significant weight advantage over conventional iron units, benefiting acceleration and brake performance in tactical or emergency response vehicles. Technicians should verify engine balance requirements and select appropriate counterweight specifications during installation to ensure optimal performance and longevity.
