The CTS Turbo crank pulley and power steering pulley are lightened to reduce parasitic drag on the engine. This results in faster revving and more horsepower. Included in the kit is the lightened crank pulley, lightened power steering pulley, and replacement bolt. The pulleys are made from T6 6061 aircraft grade aluminum and hard anodized to reduce wear. Gains of 5-7 horsepower can be expected.
