Overview:

NOTE: This bracket REQUIRES an installation kit for assembly (Part 21-1, 21-2, OR 21-3, see Fitment Guide below for the correct installation kit for your application). 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, power steering pumps and A/C compressors • A/C brackets position the compressor high above the cross-member but below the hood line for easy installation and great looks • A/C brackets are also a bolt on solution to relocate A/C compressor on engines using a GM Corvette accessory drive system • A/C bracket accepts GM R4 compressor (Sanden version now available) • 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.

    My everyday, everywhere laptop bag
    Color: Brown Pu 239
    This is hands-down my favorite laptop bag. It’s exactly as pictured. I use it daily and it has traveled all over the world with me. After a full year of hard, everyday use, it’s still holding up beautifully with no signs of wear. It holds a lot without feeling bulky. I’m able to carry my laptop along with content creation tools, marketing materials, chargers, and extras with ease. The two external pockets are incredibly helpful for quick-access items, and the two side drink pockets get used constantly—I often stash an umbrella or spare battery packs in them. One feature I really appreciate when traveling is the snap closure at the top. It’s a small detail, but it adds peace of mind when I’m moving through airports or traveling abroad and want an extra layer of security. It’s also surprisingly versatile style-wise. I carry it with casual outfits and professional attire, and it works with both. Trendy, practical, and thoughtfully designed. If you’re on the fence, get the bag. It’s well worth the cost in all categories. It’s reliable, well made, and clearly designed for real daily use.

    Amazing!
    Color: Brown Pu 239
    So cute and sturdy. Has good amounr of space and the material is quality. Great value for money and functions as a school backpack, travel bag, or just a cute carey back. Very light and slim.

    Stylish and Functional, But with a Minor Quirk
    Color: Brown Pu 239
    I really love this PU leather backpack purse! It’s a perfect mix of style and practicality, but there’s one small design issue that keeps it from being perfect. **Pros:** - **Stylish Design:** The leather finish looks chic and goes well with any outfit. It’s versatile enough for casual outings or work. - **Spacious and Organized:** The compartments are thoughtfully designed, with plenty of space for all my essentials without feeling bulky. - **Comfortable to Wear:** The adjustable straps make it easy to carry as a backpack, and the weight distribution is great. - **Durable Material:** The PU leather feels high-quality and holds up well to daily use. **Cons:** - **Top Handles Issue:** The top handles stand straight up when I wear it as a backpack, which can look a little awkward and get in the way. It’s not a dealbreaker, but I wish they could lay flat. Overall, this backpack purse is a fantastic buy, especially for the price. If the top handle design doesn’t bother you, it’s an excellent addition to your wardrobe. Stylish, functional, and durable!

    Stylish laptop backpack
    Color: Black239pu
    Chic backpack that holds a suprising amount of stuff. I needed a nice looking backpack for my laptop (Macbook Air 13") and accessories. It's sleek looking for work conferences and the top handles allow you to hold like a purse. I know some reviewers don't like the look, but for me, I like this feature. I have the black one and it has a nice quilted leather look. The straps have good padding and I was comfortable traveling all day. Even after walking several blocks in the rain there was no damage and everything inside stayed dry. The zipper and hardware are a good quality.

    Perfect lightweight computer bag!
    Color: Khaki239
    Awesome lightweight bag. Very cute. Seems durable and well-made at a very good price. Has a ton of well placed pockets that keep me organized. I purchased this as a replacement for a much heavier, computer bag and this absolutely does the trick. It looked a little small when I received it, but it holds everything that I need and more. I have a 15.6 inch laptop. I highly recommend.
