Overview
This pulley features a 5.5-inch diameter with one groove and is designed for use with a long water pump. It is constructed from 6061-T6 aircraft grade aluminum and finished with a clear powder coat for durability and a clean appearance. The pulley is also an underdrive type, which can help increase horsepower by reducing accessory rotation effort.
