Designed to handle high torque & vibration, March Performance High-Mount Serpentine Pulley Kits are CNC-machined from 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 and fan speed to help during slower driving conditions.
Applications:
- Small Block Chevy
- 1955-Earlier Cars and All Full-Size Trucks
- Requires 15'' from center of water pump shaft to hood
