Holley 20-186BK LS Mid-Mount Complete Accessory Drive System

Holley 20-186BK LS Mid-Mount Complete Accessory Drive System

Holley designed this Black 20-186BK Mid-Mount Complete Accessory System for GM LS engines. This system comes with everything you need: Water Pump, Alternator, P/S pump with Reservoir, Crank Damper, as well as the Tensioner Assembly.

All pulleys and the belt are supplied. Even heater hose adapters, power steering to -6 AN hardline, as well as the alternator plug/harness are included. Easy assembly was a priority during the entire development of this accessory solution. Color graphical instructions walk you through every step of the ultra-easy installation.

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, where the accessories bolt directly to the water pump for a clean, integrated form. The design offers superb engine visibility to show off your horsepower, not your accessories!

Among the many swap friendly features are bottom heater outlets for clearance in tight applications. The Holley designed alternator is just as innovative. This premium alternator utilizes 6-phase technology as found on the C7 Corvette. The water pump also shares its design efficiencies with that of the C7 Corvette. The compact and reliable Type II P/S pump with baffled reservoir are also integrated.
