This is the complete installation hardware kit for the Magnuson/TRD Supercharger system for the 5VZ-FE 3.4L Supercharger Kit. It includes all the hardware needed to install a newer black version of the supercharger kit. This is the same parts kit included in a new supercharger kit.
If you have the older/original GRAY version, you will need to add the mounting bolts that are not used in the new version by selecting the option to include the mounting bolts.
Note: Does not include the dynamic tensioner or the hardware to install the dynamic belt tensioner.
