Overview:

Ideally suited for bracket racers and weekend warriors alike, Q-Series carburetors are purpose-built for the dragstrip. To combat the g's experienced during hard launches, Q-Series carbs are equipped with notched floats and secondary jet extensions. The high-flow aluminum main body isn't just lightweight, but it also features recessed air bleed cavities for improved air flow. Die-cast venturi are machined to exacting tolerances for outstanding throttle response. Billet metering blocks ensure a uniform fuel curve, while throttle-bodies enhance durability. For those days when track conditions vary from one pass to the next, QFT's QuickLink system makes adjusting the secondaries easy on models equipped with mechanical secondaries. The Q-Series is our most comprehensive line of carburetors, with applications available for use with gasoline, methanol, and E85 fuels, forced induction, drag race, circle track, and comes in both vacuum and mechanical secondary models. Lightweight aluminum main body Vacuum and mechanical secondary models available Aluminum fuel bowls with dual sight glass windows Billet metering blocks with 4-corner idle system Changeable idle feed and power valve channel restrictions Billet aluminum throttle body provides exceptional precision and strength PTFE coated and sealed shafts

    Nice looking, quality is iffy 🤷🏻‍♀️
    Size: 7, Color: Black Leather
    Love the look of these, nice and comfortable, or so I thought. I wore them for the first time yesterday and they rubbed the top of my foot. I hate that they are lined in a fabric that causes friction. I kept them because I loved the look of them, but, in all honesty I think they are expensive for the quality. My right shoe has scrub marks on the leather :-(

    NICE QUALITY
    super comfortable and looks just like the picture. I usually wear 8 1/2, but since Hey Dudes don't have 1/2 sizes I purchased an 8, they fit perfect and still feel a little roomy.

    Great quality, Highly Impressed!
    Size: 12, Color: Light Brown
    These are of great quality and surprisingly comfortable. This is my first pair of HEYDUDE. I am really impressed! They are true to size. They fit my wide feet without any issues and they are my new absolute favorites! Super lightweight, extra stylish with the platform lift, and completely worth it. The color matches the photos.
