These pulley sets are available in three ratios; Performance for limited street/racing applications, Mid Performance for weekend street/track and High Waterflow for daily drivers. Precision CNC machined from 6061-T6 aluminum for extra strength, wear and to run perfectly true. Finished with a ''No Polishing'' clear or protective silver powdercoat for a maintenance-free finish!

Performance Ratios
Uses a smaller performance crank pulley and larger water pump pulley to increase horsepower by reducing accessory drag, with typical gains of 12-15 horsepower at the rear wheels.

Mid Performance Ratios
Uses performance crank pulley to decrease accessory speed to increase horsepower and a high water flow water pump pulley to maintain cooling.

High Water Flow Ratios
Increases cooling by speeding up water flow and fan speed. This helps at critical low speed driving where most overheating occurs.
