Holley Mid-Mount complete accessory systems finish the LS trilogy. Their previously released high-mount and low-mount systems are now joined with this third option of accessory solutions for LS engines. The heart of the mid-mount system is the patent-pending "bracket-less" design that permits accessories to bolt directly to the water pump for a clean, integrated form. This Holley design offers superb engine visibility to show off your horsepower—not your accessories. Holley Mid-Mount complete accessory systems have many swap-friendly features and share several design efficiencies with that of the C7 Corvette. And they are truly "complete." The mid-mount systems come with everything you need—all accessories, all pulleys, the belt, heater hose adapters, power steering hardline, and the alternator plug/harness, as well as color graphical instructions. Holley offers two systems. The premium systems come with billet dress-up tensioner and pulley covers, and SFI-certified dampers with hard anodized billet crank pulleys. Holley Mid-Mount complete accessory systems are ready for the racetrack or for anything on the street.

* Bracket-less accessory mounting with ultra-easy assembly
