These pulleys are precision made from domestic USA 6061-T6 Billet Aluminum. They have undergone thousands of hours in testing, race use, and street miles accumulated to show these pulleys work great and give you the edge. Each is precision zero-balanced and inspected for zero-runout for the best performance and to have no adverse effects on reliability, noise, or vibration. This 3 Pulley Race Set is a very popular choice: just like the 2 pulley set, a precision power steering pulley and water pump pulley are included, but VAC includes an additional underdriven alternator pulley for maximum power output on the track. We have seen 11hp and 9 ftlbs to the wheels on otherwise stock racing cars with this kit.
