Edelbrock Enforcer systems include a newly designed assembly with Eaton Gen VI 2300 TVS internals, manifold, drive pulleys, 10-rib serpentine belt and all the necessary hardware. Complete systems are pre-assembled for an easy bolt-on installation. Enforcer system part #15111 will come with a high quality polished aluminum finish. Enforcer systems are designed to be installed on a factory style front end drive and pulley system. Will not work directly with aftermarket serpentine systems.

Systems come with Corvette belt offset setup and Corvette crankshaft drive pulley adapter.
