Holley LS Gen III/IV Mid-Mount Race Accessory Drive Kit - 20-187

LS Engine Drive includes Alternator, Tensioner, Crank Damper, Belt, & Pulleys

Holley's Mid-Mount Accessory Drive System is now offered for the serious racer in mind. If you need a front drive system for your LS engine racecar, they are now available without air conditioning and power steering depending upon your needs! 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 Mid-Mount drive completes Holley's trilogy of accessory solutions giving a third option compared to the High and Low-Mount previously released. All three accessory solutions are for LS engines. When we say "complete", we mean complete. The Mid-Mount system comes with everything you need. All accessories are included; the water pump, alternator, and the crank damper. All pulleys and the belt are supplied. Even heater hose adapters, and the alternator plug/harness are included. Easy assembly was a priority during the entire development of this accessory solution. Color graphical instructions walk you through every step of the ultra-easy installation. This system is ready for the racetrack if you want to play or just be ready for anything on the street. 

Features:

  • Bracketless accessory mounting with ultra-easy assembly
  • Bottom outlet heater hose options for swap application clearance
  • LT1 style premium 150 amp alternator
  • LT1 style water pump cartridge design
  • Steam tube input port
  • Shortened top outlet nipple for more radiator hose turns and routing room
