LS Swap Accessory Drives

LS Accessory Drive Bracket - Driver's Side P/S & Alt Bracket

PART #: 20-135

UPC #:




NOTE: This bracket MAY REQUIRE an installation kit for assembly (Part 21–2 OR 21–3, see Fitment Guide below for details).

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 are also available
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.
For applications without A/C or using factory A/C bracket
