LS Accessory Drive Bracket - Installation Kit for Long Alignment(use with LONG belt alignment (alignment common on Trucks & '10-UP Camaro)

Holley accessory drive installation kits provide proper spacing for Holley A/C, P/S & Alt accessory drive brackets, so belts ride at the perfect distance on your particular engine.

A Fitment And Required Components Guide helps you locate and source components and provides other notes and helpful hints to figure your distance. Three easy steps will get you going. Step one is to determine your belt alignment based on your crank pulley position on the engine you have. Step two is to choose the Holley accessory drive brackets that you need (A/C, Alt & P/S or both). Step three is to see which Holley installation kit your set-up requires to line up your accessories with your crank pulley position. An application specific installation kit (part # HLY21-1, HLY21-2, or HLY21-3) is REQUIRED for most applications.

Holley has been the undisputed leader in fuel systems for over 100 years. Holley carburetors powered every NASCAR Cup team and nearly every NHRA Pro-Stock champion for four decades.
