    March 1984-1991 Corvette Small Block Serpentine Pulley Kits are precision CNC-machined from solid billet aluminum or high-carbon billet steel for 1984-1991 Chevrolet Corvette small block engine applications. They are computer designed for each application assuring that the electrical and cooling systems function properly while your engine runs easier, the no-slip deep grooves eliminate belt squeal and throwing!




    Performance Series
    Increases horsepower by reducing accessory drag (typically 12.5 HP at rear wheels) and eliminates belt throwing. Designed for normal street driving.

    Power & Amp Series
    Increases horsepower by reducing accessory drag (typically 11 HP at rear wheels). Designed for vehicles with automatic transmission or high-amperage need. Excellent for towing and stop-and-go driving.

    Steel Pulleys are precision machined to run perfectly true. The high-carbon billet steel is covered with iron phosphate and then powdercoated high-gloss black polyester for maximum rust prevention.

    Aluminum Pulleys are precision machined from 6061-T6 billet aluminum for extra strength and wear. They are hand polished and powdercoated clear or black for a maintenance-free finish.
