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 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 integratThe 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
