  Non-Slip Twin Screw Style Interchangeable Pulley System  

    Our New SFPH - Twin Screw Style Interchangeable Supercharger Pulley Systems are made from and incorporating a Steel Hub Assembly and a 6061 T6 Aircraft Aluminum Pulley Ring 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 pulley unit design 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, 02-current Harley F-150 or 03-current Cobra!
NOTE: We do recommend the use of our Billet Idler Pulley/Bracket Kit when using any smaller Supercharger Pulley, smaller than 3.00" for better "Belt Wrap" and "Optimal Boost Performance"
