For Consistent RPM. You want your Mustang to perform with consistent power even under intense performance driving conditions. That’s why you need the Steeda Billet Idler Pulleys that have been designed specifically for the Ford Mustang GT. Primarily, it helps solve the problem with supercharged vehicles that arise when the tensioner is put under a lot of stress. When this happens, the RPM could suddenly drop when you step on the clutch to shift to the next gear. That’s what these heavy-duty billet idler pulleys aim to solve. They help the tensioner withstand constant stress to provide more consistent power to your car.

Heavy-Duty Construction. The Steeda Billet Idler Pulleys are made to withstand incredible amounts of tension. That has been made possible with their heavy-duty 6061 aluminum construction and aggressive machined finish. And because they are made from billet aluminum, they are lightweight yet extra strong to help prevent the belts from breaking under extreme tension from high performance driving situations.

Direct Fit Replacement. The bearings in these pulleys are engineered to the exact specifications of your Mustang and are double sealed for long-lasting use. They are compatible with 5.0 engines and with the Steeda Billet Water Pump Pulley.

Application. The Steeda Billet Idler Pulleys are manufactured to specifically fit all 2015-2017 Ford Mustang GT models.

    Great power add!!

    This product gives the car more power as you shift. It is always better to install it when going for bolt ons.
