ECS 8 Rib To 10 Rib Conversion Kit Direct Drive System With 10 Rib 2.95 or 2.75 Supercharger Pulley

8 Rib To 10 Rib Conversion Kit Direct Drive System With 10 Rib 2.95 or 2.75 Supercharger Pulley

This ECS package moves a C5 or C6 Corvette supercharger from an 8-rib to a 10-rib belt using the ECS direct drive system. The goal is more belt grip and less slip as boost rises, with the supercharger driven first and the accessories carrying less load. ECS says it has what you need to max out a Paxton 1500 or step up to a Paxton 2200.
