Holley GM LS Alt & P/S Only Serp Bracket Kit for GM LS Engines

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
• Complete accessory drive kits include all components and accessories and will be available fall 2012
• 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 (CLICK ON Documents Tab) helps you locate and source components and provides other notes and helpful hints. A Holley installation kit is required to line up your accessories with your crank pulley position (See Links listed below).
