Holley 20-221 Premium Mid-Mount Complete Accessory System, GM LT4

Holley's complete accessory systems for LT4 and LT5 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.Patent - www.holley.com/patents/
