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

    Too small
    Material Type: Gray - 3 Pairs, Size: X-Large
    Too tight! Even size large used for a man with smaller feet is too tight. Also, no instructions for use or care.

    Good fit
    Material Type: Black - 3 Pairs, Size: X-Large
    My husband just started using these and they feel comfortable. Hasn't used them long enough to see if his heels are better. He has a high arch so I bought him the XL and they fit perfectly.

    No more painful cracked heels! These really do work!
    Material Type: Black - 3 Pairs, Size: X-Large
    These really do work well. This is one of the first winters that I have not experienced painful, cracked heels. They are long lasting, and definitely make my heels smoother and softer after wearing them. For the first few times wearing them I simply went with the moisturizer embedded in them. After a few uses I then covered my heels with Aquaphor Advanced Therapy Healing Ointment. This worked even better, and I would recommend it. I am very glad I bought these. Of note, I have really big feet that are quite wide and the XL are a little snug but not uncomfortably so. I use them overnight, but also have worn them under socks and they work fine.

    Wonderful for dry feet
    Material Type: Black - 3 Pairs, Size: X-Large
    I have been dealing with dry skin and problems with the heel of my foot, so I thought I would give these a try. I am so glad I did. They moisturize beautifully. A must is you are having trouble with your feet.
