    M113K 180mm Pulley Ring


    Availability: Out of stock


    M113K 180mm Pulley Ring

    The 180mm pulley ring overdrives the OEM supercharger by 20%, allowing for significantly increased horsepower and torque numbers. A tune is required when using the 180mm pulley. We recommend our M113K ECU Upgrade. We do not offer any sizes larger than 180mm because the stock supercharger would be pushed far past it's efficiency range, producing excessive heat, and ultimately reducing power gains. If you desire more power, our M113K Supercharger System Upgrade is the solution.

    This Pulley is made to pair with our M113K Modular Supercharger Pulley. This page is where you purchase an additional supercharger Pulley Ring for customers that already have our M113K Modular Supercharger Pulley.

    180mm Pulley ring requires a 55.75" belt when running the stock AMG Kompressor
