An easy bolt on that yields 12 to 15 HP. This lightweight aluminum kit provides dramatically less parasitic drag from your accessories means more power can go to the rear wheels. These are no gimmick...they work like a charm!

When over driving your supercharger there is a tremendous amount of pressure put on the belts to keep them in contact with the supercharger spinning upwards of 15,000 RPM or higher. The stock supercharger and jack shaft belt tensioners are simply NOT up to the task so we are now offering a pair of heavy duty tensioner springs for these tensioner arms. This item includes two springs. One for the crank to jackshaft belt, and one for the jackshaft to supercharger belt.
