Holley Mid-Mount Accessory Drive System Kit - 20-220BK

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. Holley's complete accessory systems for GM LT-4 applications have all accessories pulled up and in tight. Plus, they add the much needed hydraulic power steering solution. There are no shortcuts here. Holley incorporates a splined dual bearing system that eliminates all belt stresses on the P/S pump's internal bearings, assuring long life. The supercharger drive maintains the original and optimized belt path and tensioner. The accessory layout is as if the original manufacturer had designed it for your swap application. Included with each drive system is a throttle body angle correcting adapter that better positions the TB for swap applications as opposed to the aggressive original application intended angles. Versions of these accessory drives are available for both wet and dry sump applications.
