The ALTA Performance pulley features a stainless steel supercharger shaft coupler with installation site aperture. Independently attached to the supercharger shaft ALTA is the first to offer Direct Torque Technology (DTT). The older design uses bolts to do the job of holding each piece together, and compressing the taper. The Direct Torque Technology (DTT) applies all twisting force from the pulley to the hub, and uses separate bolts to secure hub to shaft. This reduces the work the bolts have to do. Our new pulley is also designed to be completely balanced with in .02 grams (better than stock), keeping your supercharger bearings happy. Direct Torque Technology (DTT) allow us to use two different materials without having problems with different material expansion rates. Our hub is made of Stainless, and the pulley body is Aluminum. The SS hub takes most of the force, and does the biggest job of securing the pulley to the shaft. The ultra light weight 6061T6 aluminum pulley body decreases rotational inertia and overall weight. Oversized belt retainers and grooved belt teeth, decrease the possibility of belts jumping off, and increase belt grip. Cooling holes are drilled into the belt retainers to keep pulley temps in check. A decorative end cap faceplate provides a clean sleek look.
