BBK SFI Underdrive Pulley System for 2005-10 Mustang GT V8.
BBK’s line of underdrive pulley systems have always been a top performance bolt-on for the popular late-model Mustang. Now owners of the latest 2005-07 Mustang GT models can bolt-on an additional 8-10 horsepower with BBK’s latest offerings.
Designed as an OEM quality upgrade to the factory system – this new kit features an SFI-approved balancer/crank pulley along with a CNC machined aluminum water pump pulley. The kit comes with complete instructions for an easy install, requires no other modifications and will deliver a slight increase in fuel efficiency by reducing power robbing accessory drag.
