Enhance performance with dual pulley system for increased horsepower and torque.
The APR Supercharger Pulley Upgrade Kit is designed to optimize the performance of your vehicle's supercharger system. By reducing the diameter of the factory supercharger drive pulley from 63.25 millimeter to 57.75 millimeter, this upgrade allows the supercharger to spin approximately 9.5 percent faster, resulting in significant gains in horsepower and torque across the entire RPM range.
Additionally, the kit includes a crank pulley upgrade that increases the diameter from approximately 162 millimeter to 187 millimeter, enabling the supercharger to operate at an even higher speed of around 15.4 percent faster. This enhancement further amplifies the performance benefits, providing a substantial increase in power output.
Constructed from high-quality materials, the drive pulley is CNC machined from billet stainless steel and features an e-coated black finish for a factory-like appearance. The crank pulley is made from lightweight billet aluminum, designed with weight-saving pockets, and is anodized black. Both pulleys are engineered to bolt onto the existing supercharger and crank pulley, retaining the factory harmonic balancer for optimal performance and reliability.
