Serpentine Pulleys
Standard Rotation Long and Short Water Pump
Replace your old V-Belt pulleys for modern No-Slip operation
Performance Ratios
Our performance serpentine pulley sets replace your Low performance V-belts and eliminate belt throwing while retaining your standard rotation water pump. Increases horsepower by reducing accessory drag. 12-15 h.p. at rear wheels typical. Precision CNC machined to run perfectly true. 6061-T6 aluminum for extra strength and wear.
Mid Performance Ratios
Uses performance crank pulley and high water flow water pump pulley.
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.
