Chevy Flywheel Aluminum HTD 65T

The Chevy Flywheel Aluminum HTD 65T from BRINN TRANSMISSION (part number 79084) is a precision-engineered aluminum flywheel designed for high-performance Chevy V8 engine swaps and transmission upgrades. This 65-tooth HTD pulley flywheel combines lightweight construction with the durability required for modified engine applications, delivering the rotating mass and engagement characteristics necessary for reliable power transfer in custom automotive builds.

Weighing 3.15 lbs, this aluminum flywheel reduces overall engine rotating mass compared to traditional cast-iron units, improving throttle response and reducing parasitic drag on the engine. The HTD tooth profile ensures positive engagement with compatible drive systems and provides consistent power delivery across the RPM range. The 2-piece seal design accommodates various bellhousing configurations common in engine conversion work, while the aluminum construction offers superior heat dissipation—a critical factor in high-output or frequently driven performance vehicles where sustained power demands generate significant thermal load.

This BRINN flywheel is engineered for Chevy V8 platforms undergoing transmission swaps, stroker builds, or power adders where OEM flywheels fall short of application demands. Whether building a street performance engine, weekend track car, or custom hot rod, this component provides the reliability and precision tolerances expected from a dedicated transmission supplier. The 65-tooth configuration is a standard reference size in the performance automotive aftermarket, ensuring compatibility with common serpentine belt systems and accessory drive layouts used in restoration and custom engine bay projects.
