Ultimate Performance supercharger pulley upgrade for the AMG 55 Kompressor motor.

Our tests show 90 plus wheel hp and torque gains, while maintaining a safe level of boost and supercharger rpm.

Pulley upgrade offers excellent drivability and does not adversely affect highway mileage.

Specs:

• Increases horsepower and torque
• 35% lighter than factory pulley, reducing rotational mass
• Reduced rotational mass increases supercharger longevity
• 74mm diameter
• Easy to install
• Special coating reduces belt slip
• Improved nitride coated clutch, plate and spring design

Tune will be needed for this pulley, as fuel and power increases will exceed factory tune parameters.
