Pulleys - Crank, Underdrive

Enhance your vehicle's performance with crank and underdrive pulleys from top brands like aFe Power, Alta, BBK, Perrin, and Torque Solution. These pulleys are designed to improve horsepower and torque by reducing the amount of effort required to drive essential engine components.

Crank pulleys, such as those offered by aFe Power and Alta, are engineered to reduce rotational mass in the engine, resulting in quicker acceleration and increased power throughout the RPM range. These lightweight pulleys are precision-machined for a perfect fit and are available for a variety of vehicle makes and models.

Underdrive pulleys, like those from BBK and Torque Solution, are designed to slow down certain engine components like the alternator and water pump, reducing parasitic drag and freeing up horsepower that would otherwise be lost. These CNC-machined aluminum pulley kits are easy to install and are a simple way to boost performance without extensive modifications.

Whether you're looking to fine-tune your Mini Cooper's supercharger, increase power in your Ford Mustang, or optimize performance in your Subaru WRX, STi, or Porsche, crank and underdrive pulleys are an essential upgrade.
