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.

    Great ball!
    Color: Ultra, Size: Large
    Our puppy loves this ball. It has held up well so far, it’s about 2 weeks now of large breed pup play. It’s been outside for the last week, rain or shine, still in working order. Not as big as I thought it would be though. No squeak, bounces well. Thick rubber like material, that can be depressed when biting down.

    Durable, even for a Great Dane!
    Color: Ultra, Size: XXL
    I've bought many tennis ball sized ChuckIt balls in the past (for medium sized dogs we've owned), so when we knew we were going to be babysitting our daughter's Great Dane, I bought a bigger one for her. The 4" is perfect for her! She plays catch with it, but also likes to gnaw on it. It holds up great!

    Another great product from Chuckit!
    Color: Ultra, Size: XL
    Exactly the high quality that I've come to expect from Chuckit! The plastic/rubber used in their products is extremely tough yet gives enough that it's hard to actually pierce the it and tear apart. We have had Chuckit! Sticks and Balls with launcher for years and love them all. This particular ball is pretty big so my 45 pound pit mix struggles to pick it up but that's part of the fun for him. My 85 pound pit mix can pick it up no problem. The only "complaint" is that the two of them have been having so much fun with their new ball, they have already knocked something over and broke it. 😁

    Perfect for my mid size pit bull
    Color: Ultra, Size: XL
    Updating my review, the ball only lasted 5 days. I left the 5 stars because we had enough fun those 5 days to be worth the small price. She has dog has a lot of jaw strength, so I’m not surprised We have a mid size foster pit bull. This ball is her favorite toy. It’s durable and the perfect size for her to play ball safely.
