M113K Clutched Supercharger Pulley
The DTK Clutched Supercharger Pulley operates like the OEM unit, disengaging the supercharger during light load and cruising while delivering increased boost under throttle.
Smaller pulley sizes spin the supercharger faster, producing more boost and power without sacrificing factory driving behavior. Our pulleys are manufactured using aircraft-grade duraluminum, paired with a steel clutch assembly and reinforced springs for long-term reliability.
Available Sizes:
From stock diameter to aggressive 68 mm options.
⚠️ Proper cooling, ECU tuning, and a belt wrap kit are strongly recommended when selecting smaller pulley sizes.
