Overview:

Serious drag racing demand a serious drag racing carburetor, and the QFX-Series stands as the flagship model in QFT's lineup. Raised air horns improve entry angle into the venturi while ensuring undisrupted flow over the air bleeds. Annular boosters with CNC-machined billet aluminum inserts provide increased air flow, a stronger signal, and less turbulence. QFX carbs offer unparalleled fuel atomization with annular boosters specific for either gas, methanol, or E85 fuels. Five-emulsion billet metering blocks and four-corner idle circuits offer flexible tunability that today's high-horsepower engines demand. To cover a broad range of applications, methanol- and E85-compatible models, as well as two- and three-circuit fuel systems, are available. Ready to run out of the box, the QFX-Series carburetor will help you get to the winner's circle.
Even a carburetor that performs great can still be an eyesore, but it doesn't have to be that way. Quick Fuel Technology's proprietary Black Diamond® coating offers excellent corrosion resistance as well as a durable finish that easily stands up to dirt and oil. In addition to great looks, the PTFE coating reduces fuel temperature by six percent for improved performance.

    Perfect for "Heavy Chewers," lasts long, and has yet to come apart or tear up
    Size: Large, Product Packaging: Standard Packaging
    I have several dogs, and they are what would be considered as "Heavy Chewers." They are truly awesome pets, and I consider them like my children. I started looking for toys that I wouldn't worry about if I didn't have line of sight for every minute. All dog toys, regardless of their size, type, weight, or if they're steel versus plastic material have a warning on the bottom of very label/package that states that the animal should never be left alone with the toy. With that said, I do not leave the toys unattended, even though this toy has paid it's weight in how well it has stood up to the constant chewing my dogs give it everytime I place it in their crates to prevent fights, or issues on the pack order. As far as the actual toy, it looks, feels, and even smells like a tire, but without any problems with the dogs accepting it to play with. The toy bounces like a ball, and the overall weight is heavy enough to ensure durability. Just like a tire, the toy is made of rubber, not plastic material. I have found that smearing small amounts of peanut butter in to the crevices of the tire rather than brand specific treats is just as effective, I will also freeze the peanut butter into the tire, and this also increases the length of time it takes for the dogs to consume. I ended up buying three more toys, mostly so all my dogs have one, and that I also have one as a spare. I would recommend this to any owner of a "Heavy Chewer" as the product is well made, and yet to have any defect or piece removed by any of my dogs, and they do chew on these toys extensively.

    Tough and Long-Lasting Toy for Heavy Chewers
    Size: Large, Product Packaging: Standard Packaging
    The KONG Extreme Tires are built for dogs who chew through just about everything else. Made from KONG’s most durable rubber, the toy is designed to stand up to strong jaws while also offering a fun shape that dogs enjoy rolling, chasing, and chewing. The tire design has grooves that can be stuffed with treats or peanut butter, which helps keep dogs engaged for longer play sessions. This toy is especially useful for large breeds or heavy chewers who usually destroy softer toys in minutes. While no toy is completely indestructible, the Extreme Tires hold up far better than most and provide both chewing satisfaction and mental stimulation. The size is hefty and best suited for medium to large dogs, and smaller breeds may find it too heavy. Pros: The rubber is extra durable, the tire shape adds variety and fun, and the grooves can be filled with treats for extra engagement. Cons: It may be too heavy for smaller dogs, strong chewers can still wear it down over time, and it isn’t designed to bounce or fly like other KONG toys. A rugged and reliable toy made for power chewers. The Extreme Tires provide long-lasting fun and double as a great option for treat-stuffing, making it one of KONG’s toughest and most useful toys.

    To small for 2 month German Shepherd. It was my bad for ordering a small. But I never saw product specs saying the actual size. Remember never buy a to small of toy for your puppy as it’s a choking hazard.
