Flywheel New Chevy HTD

The Flywheel New Chevy HTD from BERT TRANSMISSIONS is a premium 1-piece steel flywheel engineered for serious small-block Chevy builds and high-performance street/strip applications. This internal-balance unit delivers the reliability and precision demanded by engine builders, transmission specialists, and enthusiasts running upgraded ignition systems or performance transmissions. Whether you're upgrading an existing engine or building a complete rotating assembly, this HTD pulley flywheel provides the foundation for consistent power delivery and durability.

Constructed from robust steel and featuring a single-piece design with an integrated 1-piece seal, this flywheel minimizes parasitic drag while maintaining structural integrity under high rpm operation. The HTD (High Torque Design) pulley geometry ensures efficient accessory drive engagement and reduces heat generation in extended-use scenarios. Internal balance design eliminates the need for external counterweights, keeping the rotating assembly compact and improving overall engine balance—critical when running tighter cylinder clearances or higher boost levels. At 4.82 lbs, this flywheel strikes an optimal balance between inertia control and lightweight construction, making it ideal for both naturally aspirated and forced-induction small-block applications.

This flywheel is purpose-built for small-block Chevy engines (262 to 400 cu. in.) and is the go-to choice for transmission shops, engine builders, and performance mechanics performing complete powertrain refreshes or racing builds. Installation requires proper balancing and alignment with your crankshaft and clutch assembly; professional installation is recommended to ensure concentricity and prevent vibration issues. Compatible with both standard and custom clutch packages, this BERT unit delivers the thermal stability and durability required for sustained high-performance use.
