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. QFX aluminum main body w/raised venturi Billet aluminum metering blocks with screw in restrictions Aluminum fuel bowls with dual sight windows and fuel inlets Nitrophyl® Floats (notched rear) and jet extensions Viton .130" Needles and Seats Billet Aluminum annular booster inserts QuickLink™ adjustable secondary opening adjustment Hand assembled and engine tested

    Great Durability
    Even my heavy chewer GSDs haven’t destroyed them…yet. Easier on your shoulder if you buy the ball thrower.

    Dog loves this ball.
    Great ball. The dog loves chasing it and it bounces in different directions so she can’t anticipate where it goes. So far she hasn’t been able to chew through the ball. She Is a medium sized dog.

    Durable, bouncy, absolutely loved!
    My dog, bless her heart, goes absolutely bonkers for these balls. I swear she knew what was in the package before I even opened it she was right there trying to open it for me. These are GREAT! We take them to the park with the Chuck-it Stick, to the river for some water fetch, and anywhere as her “reward” for being calm and obedient. Beware though, they sure can BOUNCE. She dropped one of these out the car window (we were going 20mph in a residential area) and even after searching for almost 10 minutes I could not find it. They can withstand her super-chewer mouth with no visible damage. I highly recommend! (Photo is of the tennis ball version of this product, she doesn’t sit still long enough for a photo of the rubber version).
