TBA Machine is now releasing the hub and pulleys we have been running and perfecting over the last year. What makes ours better is the unique .875” hex drive system for the the supercharger pulley. Instead of 6 tiny bolts that are holding the drive force of the pulley, the TBA Machine pulley relies on the precise fit of the 316 stainless supercharger hub to drive the pulley. Therefore, when you need to change pulley, you do not have to worry about the bolts being stuck, broken or bent from the rotational force of supercharger pulley. All our hardware does is hold the pulley to the hub. The pulley and hub are sold as a kit only since our proprietary design is not compatible with other brands. If you are in to the “sleeper look” we even machined the front cap cover so the rubber block off seal off of the stock supercharger pulley will fit. It is not mandatory to use this feature but the option is there is you choose to use it. All pulleys are hard coat anodized for a lifetime of use.
All supercharger pulley changes require modification by a tuner and a belt change. The PCM must be updated to accommodate the increased boost levels. Please see our combo packages to purchase the complete kits with all of the tools and the belts.
