Product Information
- Precision machined from high grade, lightweight aluminium castings
- Extra-deep belt grooves provide added belt retention during rapid changes in engine RPM
- Small pulley diameter slows fan, water pump, and alternator speed to reduce horsepower-robbing drag
- High RPM water pump operation is improved, reducing impeller speed below cavitation threshold
- Use 36° x 17/32" wide belt
