The Moddbox Supercharger Pulley Kit includes two CNC precision cut, bead blasted, anodized, and laser engraved Moddbox Pulleys (the 54.04 and 55.35 mm diameters). These pulleys are precision machined from T6061 aluminum which conforms to QQ-A-200/8 and ASTM B211 ensuring a high strength-to-weight ratio as well as increased corrosion resistance and durability. The pulleys come with the Moddbox Patented Pulley Drive Coupler which is engineered and manufactured to provide a reliable high-performance product that is easy to install and of the utmost quality and durability. The coupler design utilizes a mechanical interference fit with uniform pressure distribution that achieves increased performance over OEM shrink or press fit designs due to the increased clamping force. Additionally, the Moddbox coupler provides a true zero backlash shaft-to-hub connection with none of the operational drawbacks of keyways, splines, or other problems common with other OEM designs.
