Flywheel Bert /Brinn 91t Chevy w/coupler 1pc Stl

The Quarter Master Flywheel Bert/Brinn 91-Tooth Chevy with Coupler (1-Piece Steel, Part #509139B) is specifically designed for high-performance Chevrolet engine conversions and clutchless bellhousing applications. This flywheel is ideal for builders and racers looking to enhance their custom drivetrains, particularly in quarter-mile performance and bracket racing scenarios.

Constructed from durable steel, this internally balanced, single-piece design provides the necessary rotational mass and tooth engagement for reliable power transfer. Its internal balance specification ensures smooth operation at high RPMs, minimizing vibration and imbalance issues. The flywheel's robust construction allows it to withstand the thermal and mechanical stresses of rapid shifts and high-load launches.

This flywheel is particularly beneficial for those implementing advanced transmission systems in Chevrolet-powered vehicles, where shift speed and engagement consistency are critical. It is compatible with Quarter Master's clutchless bellhousing kits, which eliminate the need for conventional clutch assemblies, allowing for dramatically faster shifts.
