Description
Holley Mid-Mount complete accessory systems achieve what no other accessory bracket systems have: eliminate the brackets! This pulls in all the accessories tighter than other accessory drives by bolting directly to the water pump for a clean, integrated form. They offer superb engine visibility to show off your horsepower, not your accessories.
These systems have many swap-friendly features and share several design efficiencies with that of the C7 Corvette—plus they are truly complete. They come with everything you need: all accessories, all pulleys, the belt, heater hose adapters, and the alternator plug/harness, as well as color graphical instructions. Holley Mid-Mount complete accessory systems are available in several versions and finishes to match your GM application. Order the kit designed to fit your engine.
Features and benefits may include:
* LT1-style hairpin premium 150 amp alternator
* LT1-style water pump cartridge design
* Compact and reliable SD7 A/C compressor
* Type II power steering pump with baffled reservoir
* Power steering adapter hardline to AN -6 adapter
* OE pulley ratios for optimal accessory performance
* Bottom outlet heater hose options for swap application clearance
