Increase boost and add tire-shredding horsepower!

Steeda's GT500 supercharger pulley directly replaces the factory supercharger pulley and gives approximately 3 PSI of extra boost.

Manufactured out of billet steel, not aluminum like others on the market, and nickel-plated for durability and great looks.

Also available for the Ford GT supercar (not shown).

In-house testing has shown increases of over 125 HP and 100ftlbs of Torque to the rear tires!!! (Tested on GT500 with Steeda CAI, Pulley, and Tune)

Notes: This product requires a custom tune. Steeda highly recommends adding a Steeda Belt Tensioner when adding an Underdrive Pulley to prevent belt slippage.
