German Muscle 76mm Clutched Pulley and Tune Combo for the M113k
Combine and save with our custom 76mm clutched Supercharger pulley and tune upgrade for the 55k platform. Our tests have shown us 50-55 rear wheel hp and torque gains while maintaining a safe level of boost and supercharger RPM. This pulley upgrade offers excellent drivability and does not adversely affect highway mileage. Our M113k 76mm clutched supercharger pulley is 35% lighter than the factory pulley which will effectively reduce rotational mass to increase your superchargers longevity. This pulley sports a special coating to reduce belt slip and is easy to install.
This combo includes the required flash tune set for your current modifications!
