Product Overview

The 168-Tooth Steel SFI 14 Inch Flywheel GM Compatible is designed for GM engines that require a large-diameter, externally balanced flywheel for proper engine operation. The flywheel connects directly to the engine’s crankshaft and plays a critical role in transmitting engine power to the clutch and transmission system.

This flywheel features a 168-tooth ring gear and a 14-inch diameter clutch surface, making it compatible with many GM drivetrain systems that use larger clutch assemblies. The externally balanced design includes a 42.5-ounce imbalance weight, which is necessary for engines that rely on external balancing to stabilize the rotating assembly.

Manufactured from high-strength steel, this flywheel is engineered to handle demanding performance conditions while maintaining durability and reliability.

Where This Flywheel Is Used

The 168-Tooth Steel SFI 14 Inch Flywheel GM Compatible is commonly used in GM engines that require external balancing with a 1-piece rear main seal configuration.

Typical applications include:

• GM small block Chevrolet engines
• performance engine builds
• manual transmission conversions
• engine rebuild projects
• racing or high-performance vehicle builds

The 168-tooth flywheel size is commonly used with GM starter systems designed for large-diameter flywheel configurations.

Performance and Function
