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.

    Best chew toy we have ever purchased.
    Flavor Name: Classic, Size: Large
    My moderately active 80lb Lab - Pit mix has been steadily working on this bone for over a year. He doesnt chew it every day but he does regularly chew it for 30 or more minutes at a time. He has only been chewing on the smooth end, and the only wear it shows is a slight thinning and some grooved tooth marks. It has not had any chunks come off, and has never developed any sharp edges that make it hard to play with. It has never smelled or gotten slimy. It has never triggered resource guarding with him, but he likes it enough that presenting it to him will often get him to settle down and chew when he is in a rambunctious mood. Its size and shape allows him to hold the textured Y end with his paws while chewing on the smooth end. All in all a fantastic toy!

    Happy Doggo
    Flavor Name: Beef, Size: Small
    He immediately loved it. He doesn't take to bones quickly, but this one caught his eye. He's a 35 lb shepherd mix, and loves antlers, and chews pretty hard. I love that it doesn't smell, and havne't seen or noticed flakes. Overall would recommend.

    Excellent product, highly recommend
    Flavor Name: Classic, Size: Large, Flavor Name: Classic, Size: Large
    So glad I came across this brand that uses actual edible material instead of the plastic nylon! All of our dogs love the nylon chew toys, but it's so bad for them to eat the little plastic bits! I got the large one & it is VERY large! I actually wish they had a medium one, one in-between the large & small ones as an option. But our dogs still love the large one, just harder for them to carry around & boy is it loud each time it gets dropped on the hardwood floor. It's big enough both the pups can chew on it together at the same time & do just that. We've had it for a couple months now & they don't chew on it everyday, but a few times a week I'd say & it's a tad bit softer than the nylon chews, but I'd say it's held up very well!

    Dogs love them
    Flavor Name: Beef, Size: Small
    My two pups are power chewers. These bones are great! There’s no smell and pieces don’t come off like other bones. Although I am not a fan of the sound it makes when my dogs chew on them (nails on a chalkboard sound to me) they love them and it keeps them entertained. They are extremely hard so I limit their chew time (only because I can’t afford a trip to the vet if a tooth gets cracked) overall satisfied with my purchase, both myself and pups!

    Excellent for heavy chewers!
    Flavor Name: Beef, Size: Mini
    My dog is between 1-2 years old, and is a heavy chewer. So far the Better Bone is lasting very well! He still is chewing away at it! Excellent quality, and I appreciate that there’s no plastic that my dog is consuming.
