Holley is pleased to offer simple, clean, cost effective solutions that
solve the accessory drive challenges encountered when swapping a GM LS
engine into a muscle car, truck, hot rod or other vehicle. These
brackets were designed to deliver a factory style appearance, correct
belt alignment and factory stability.
Key Features:
• The most cost effective LS bracket solution on the market!
• Universal brackets fit virtually all common LS engines regardless of
water pump and harmonic balancer offsets reducing cost and complexity
compared to competitive products
• Simple, dedicated installation kits allow easy fitment to Corvette, F–Body or Truck drive offsets
• Utilizes commonly available and affordable GM alternators and power steering pumps
• OEM quality natural finish die castings for clean looks and durability. Can be polished, coated, painted or plated.
• OEM spec flanged head hardware included to match your factory LS engine hardware
• Ideal for crate engines, take out motors and engine builders!
Holley's kits supply the required brackets and hardware needed for
installation, but allow you to choose the source for supplemental
accessories and components that are often already on the donor engine or
host vehicle. Whether sourcing from the salvage yard, the local auto
parts store, your GM parts dealer, or Holley, you pick the accessories
that match your needs and budget!
A Fitment And Required
Components Guide helps you locate and source components and provides
other notes and helpful hints. 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 # 21–1, 21–2, or 21–3) is REQUIRED for most applications.
