Pulley 2V Chrome 2 5/8in OD

The Pulley 2V Chrome 2 5/8in OD from POWERMASTER is a precision-engineered alternator pulley designed for V-belt drive systems in high-performance and street rod applications. This two-groove pulley replaces worn or undersized original equipment, restoring proper serpentine belt tension and alternator output efficiency. Built for builders and enthusiasts who demand reliable charging system performance, this pulley integrates seamlessly into POWERMASTER alternator installations where belt drive geometry and pulley diameter directly influence charging amperage delivery and engine accessory reliability.

Constructed from steel and finished in durable chrome plating, the Pulley 2V Chrome 2 5/8in OD features a 2.625-inch outer diameter and dual V-belt grooves for secure belt engagement. The chrome finish resists corrosion and oxidation while delivering a polished appearance under the hood. The two-groove design accommodates standard automotive V-belt profiles, and the OD specification ensures correct pulley ratio and belt speed synchronization. Weighing 1.26 pounds and measuring 3.3 x 2.3 x 3.7 inches, this pulley is compact enough for tight engine compartments while maintaining the structural integrity required for sustained high-RPM operation.

This pulley is ideal for custom engine builders, hot rod restoration shops, and alternator upgrades on classic or modern vehicles equipped with POWERMASTER charging systems. Proper pulley diameter is critical—undersized pulleys reduce alternator RPM and charging output, while oversized pulleys can over-speed the alternator and reduce component lifespan. Installation requires removal of the serpentine belt and existing pulley; alignment with the crankshaft and other accessory pulleys is essential for noise-free operation and belt longevity. Verify compatibility with your specific POWERMASTER alternator model and belt routing before ordering to ensure correct fit and performance.
