Non-Slip Twin Screw Style Interchangeable Pulley System

South Florida Pulley HQ

Our New SFPH - Twin Screw Style Billet Aluminum Interchangeable Supercharger Pulley Units 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 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"
