The Leggdura Racing Lug Nuts

Kics is proud to announce the release of an all new racing lug nut. It's called LEGGDURARACING. Derived from the Italian word "leggero" for light and "duralumin" for its material composition, the LEGGDURA RACING lug nuts are made in Japan from forged A7075-T6 Aluminum alloy. Weighing a mere 22 grams per lug nut, the 20 piece set (16+4 locks) is less than 0.25 pound per wheel corner compared to stock weight of 0.50 pound per corner. That’s a 50% total weight savings which can help increase the performance aspects of braking, cornering, and acceleration.

  1. Super nice lugs!

    By Super nice! April 2, 2022

    I had to extend studs on my car so I was on a hunt for lugs. I started with another reputable brand but after removing them a couple times they were already getting marred up and didn’t look very nice so I kept hunting. These are pricey for some lug nuts, ngl I was pretty hesitant but I bit the bullet. Glad I did these were what I was looking for. The 2 piece design is cool, they look great and most importantly they were quality so I don’t have to worry about them messing up the studs I replaced either. Worth the money. Buy once cry once, should have gone this route to begin with.

  2. Look great

    By Nica April 9, 2021

    These things are awesome and look great. Paint doesn't scratch or chip easy. I like the added security of the wheel locks but getting these on/off is kind of annoying. The tool they provide to take the shell off breaks easy, so I just use my own socket now. However, in order to take these on/off I need a different sockets for the shells, the lug nuts and the key for the lock. They're all different sizes. So while it's a pain to take on/off, I know no one's gonna have to time to steal my wheels lol

  3. Absolutely Perfect

    By Demariners June 8, 2018

    Love these lugs. Actually everything by project kics are terrific. What I really like about these is the 2 part design. You can't scratch these if you install them correctly. They are well built and are stunning. I think anyone that has custom wheels should have these.

  4. Quality

    By Edian April 10, 2018

    They looks awesome and love the fact that they are a 2 piece lug nuts.

  5. Very clever design

    By Chad November 30, 2017

    I am very pleased with the quality and finish of these, as well the added security of keeping my forged wheels in their place.
