Non-Slip Twin Screw Style Supercharger Pulleys

South Florida Pulley HQ

Our New SFPH - Twin Screw Style Billet Aluminum Supercharger Pulleys are now available with our Special Non-Slip Grooved Design in SC Pulley sizes 2.50", 2.75", 3.00", 3.25", and 3.50". This will help eliminate ANY and ALL belt slippage problems which are associated with using smaller supercharger pulleys on any Kenne Bell Supercharger, installed onto a 99-Current Ford Lightning or 03-current Cobra!

The Stock Kenne Bell Steel SC Pulley weighs 1.5 lbs... our SFPH Pulleys weigh 7.3 oz. each! Less rotational mass weight equates into supercharger spinning up a lot quicker and you experience more consistent horsepower gains, compared to the stock steel pulleys that come on any Kenne Bell Supercharger.

The SFPH - Twin Screw Style Non-Slip Billet Aluminum Supercharger Pulley is manufactured on a CNC Machine and is manufactured from 6061-T6 Billet Aluminum for Superior Strength and Longevity, for many years to come.
