Designed to handle high torque and vibration, March Performance Inward Mount Serpentine Pulley Kits are CNC-machined from solid 6061-T6 billet aluminum for a perfect fit and powdercoated clear for lasting good looks. The pulleys will not fracture like common cast pulleys, and their Street Rod Ratio increases water flow & fan speed to help in slower driving conditions.
Applications:
- Small Block Chevy
- Requires 13'' from center of water pump shaft to hood
- 1969-84: Passenger cylinder head needs tapped (1985-Up: Bolt on)
