Since 1988, BBK Performance has been a leading brand in bolt-on performance upgrades for modern muscle cars and trucks. Founded by Brian & Ken Murphy, BBK was the first to design aftermarket air intake systems and performance throttle bodies for the newly fuel-injected 5.0L Mustang and TPI Camaro models. Today, BBK is known for its high-quality performance products that cater to enthusiasts who are looking to upgrade their vehicles while maintaining OEM quality and drivability.
The BBK Underdrive Pulley System is part of the Power-Plus Series and is designed to provide a simple way to gain approximately 8-10 horsepower. Made from CNC machined billet aluminum, this 2-piece kit includes a crank pulley, alternator pulley, and all required hardware for installation. The direct replacement pulley kit requires a new, shorter length serpentine belt and will not affect the cooling or charging of the vehicle.
The premium quality lightweight crank pulley adds both great looks and performance to your vehicle. This 2-piece kit includes the crank pulley only, along with all necessary hardware and instructions for a simple installation process.
BBK is proud to be an American designed and built brand, with state-of-the-art facilities in California and Florida. With years of research and development, BBK has become the largest source of modern-day performance products for today's cars and trucks. If you own a modern Dodge, Ford, or GM vehicle and are looking to upgrade your performance, BBK is the number one aftermarket performance brand in the USA.
