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 millimeters to 57.75 millimeters, this upgrade allows the supercharger to operate 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 millimeters to 187 millimeters, enabling the supercharger to spin around 15.4 percent faster. This enhancement further amplifies the performance benefits, providing a substantial increase in power output. Both pulleys are constructed from high-quality materials, with the drive pulley made from CNC machined billet stainless steel and the crank pulley from lightweight billet aluminum, ensuring durability and efficiency.
The pulleys feature an anodized black finish and are e-coated for a factory-like appearance. The design retains the factory harmonic balancer and is a straightforward bolt-on installation, making it accessible for those looking to enhance their vehicle's performance without extensive modifications. This upgrade kit is an effective solution for those seeking to maximize their supercharger's potential.
