6061-T6 Billet Aluminum Harmonic Balancer Crank Pulley

The VMS Racing crank pulley is designed as a direct-fit, lightweight performance upgrade for 1993-2001 Honda Prelude models equipped with 2.2L DOHC VTEC H22A1 and H22A4 engines. By reducing the mass of the rotating assembly, this component helps improve throttle response and overall engine performance without the power-robbing issues associated with underdrive pulleys. Constructed from high-strength 6061-T6 billet aluminum, the pulley is precision CNC-machined to tolerances within .001. It features a type 3 hard-anodized finish in gun metal matte. Unlike many aftermarket underdrive options, this unit maintains the original factory diameter, allowing for the use of stock-length drive belts and ensuring that engine-driven accessories operate at intended factory speeds. Installation is straightforward as the unit mimics the OEM configuration and includes integrated timing marks for easy engine adjustment. Note that while this part is designed for the specified H22 engines, users swapping in different crankshafts (such as the H23A1) may require a different belt length due to subtle differences in pulley size.
