This is used only if you have the low boost supercharger currently and you would like to upgrade to a high boost supercharger. High boost pulley not included. When placing your order, please place your vehicle information in the comments box in the check out. We need to know what vehicle and year it is so we can include the correct vehicle specific installation guide.Also please select which supercharger you have. The 1st Gen units were GRAY, and the current 2nd Gen units are BLACK. This info is needed because the fuel line is different for each supercharger.
For High-Boost pulley go to Part# 1016160.
