LS7 Engine Drive includes SD7 A/C Compressor, Alternator, P/S Pump, Tensioner, SFI certified damper w/hard anodized billet crank pulley, Belt, & Pulleys - Fits Dry Sump Engines.
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 SD7 A/C compressor and Type II P/S pump with baffled reservoir are also integrated.
NOTES: "The power steering pump included can be used Hydroboost systems. Please refer to the flow specs on part number 198-101 This accessory drive is for LS7 & LS3 Dry Sump engine applications

FAQs
|Q. What is an Intermediate Brake Line?
