Holley's Premium Mid-Mount complete accessory system has all accessories pulled in tighter than other accessory drives. At the heart of the system is a bracketless design (Patent Pending), where the accessories bolt directly to the water pump for a clean, integrated form.

The Mid-Mount drive completes Holley's trilogy of accessory solutions giving a third option compared to the High and Low-Mount previously released. All three accessory solutions are for LS engines.
When we say complete, we mean complete. The Mid-Mount system comes with everything you need. All accessories are included; the water pump, alternator, and the crank damper. All pulleys and the belt are supplied. Even heater hose adapters, and the alternator plug/harness are included. Easy assembly was a priority during the entire development of this accessory solution.
