Chevy Flywheel HTD 65T New Style

The Chevy Flywheel HTD 65T New Style from BRINN TRANSMISSION is a precision-engineered crankshaft coupling component designed for Chevy V8 engines undergoing serious performance modifications. This HTD (High-Torque Drive) pulley flywheel serves as the critical interface between your engine's crankshaft and supercharger, turbocharger, or belt-driven accessory systems. Built for builders and performance shops, the 65-tooth configuration provides reliable synchronization in high-demand applications where standard flywheels fall short.

Machined from durable steel, this 1-piece sealed flywheel eliminates the weak points found in multi-piece designs, reducing vibration and ensuring consistent belt tracking under sustained boost and load cycles. The HTD tooth profile—tougher and more angular than standard V-belt grooves—grips serpentine belts with superior holding power, critical when you're running elevated horsepower numbers or forced-induction setups. At 5.2 lbs, the BRINN design keeps rotating mass conservative while maintaining the structural integrity required for repeated high-RPM cycles, making it ideal for street/strip vehicles that demand reliability alongside performance. The new-style geometry accommodates modern Chevy V8 configurations with factory-style bolt patterns, simplifying installation and maintaining OEM cooling and accessory mount compatibility.

Performance enthusiasts, engine builders, and shops tackling turbo or supercharger installations on small-block and big-block Chevy platforms benefit most from this component. Installation pairs directly with serpentine belt systems and requires no special tooling beyond standard crankshaft-locking procedures. The 1-piece seal design prevents oil weeping at high temperatures, common with pressed or multi-segment alternatives. Verify fitment against your specific V8 displacement and accessory drive configuration before ordering, as Chevy engine families have evolved across generations.
