Description
The aFe POWER Supercharger Power Pulley Kit with Hub (2.85") is engineered to increase supercharger boost and maximize horsepower for high-performance 6.2L supercharged HEMI engines, including Dodge Challenger SRT Hellcat/Demon/Redeye, Charger SRT Hellcat, Durango SRT Hellcat, Jeep Grand Cherokee Trackhawk, and Ram 1500 TRX. Designed for enthusiasts seeking a precise, bolt-on solution, this pulley kit allows you to adjust the supercharger spin rate, delivering an approximate 3 PSI increase in boost for enhanced acceleration and throttle response.
The kit features a CNC-machined 6061-T6 aluminum pulley with a black hard-anodized finish, combining lightweight design with exceptional strength. A laser-etched logo and sizing ensure both aesthetics and accuracy. The included CNC-machined 17-4 stainless steel hub provides corrosion resistance and durability, while maintaining a perfect fit and flawless finish. All necessary screws, washers, and thread locker are included for secure installation.
To accommodate the higher spin rate, a smaller serpentine belt (Gates K100572HD) is required, and professional installation is recommended due to the specialized tools needed to remove the factory pulley. Tuning is required to optimize engine performance and safely integrate the new boost levels.
