Holley 20-185 COMP MID-MT ACC SYSTEM, LS-NATURAL

Holley COMP Mid-Mount Accessory System for LS Engines

SKU: HOL20-185

The Holley Mid-Mount Accessory Drive System Kit features a natural finish and a bracketless design for GM LS engines. It comes complete with an SD7 A/C compressor, alternator, power steering pump, crank damper, tensioner, belt, pulleys, and hose adapters for a streamlined, all‑in‑one installation.

Holley's 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 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 hairpin/square wire, 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 SD7 A/C compressor and Type II P/S pump with baffled reservoir are also integrated. 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, A/C compressor, Alternator, P/S pump with reservoir, and the crank damper. All pulleys and the belt are supplied. Even heater hose adapters, power steering to -6 AN hardline, and 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.
