    ITS A MUST HAVE
    NOT MUCH I CAN SAY AT THIS POINT, I HAD TO HAVE THEM TO FIT MY STI WHEELS, ONLY BEEN ON A FEW WEEKS BUT LOOK GOOD FOR NOW. NOT CRAZY ABOUT NEEDING TO KEEP TRACK OF A LUG KEY BUT AGAIN DIDNT HAVE A CHOICE WITH THE WHEELS I CHOSE.

    Locking vs. non-locking - Wheel required
    Actually, I bought this for my spare wheel and tire because the wheel bolt pattern holes were too small to take the factory nuts. I did not want a different nut, but the new wheel required it. When buying a new wheel be sure to check that kind of thing. I didn't and had to go back to find something that would work.
    Application was for an RZR 900 trail.

    I love the STI rims but these lugs aren't that great
    I am sure there is a reason for this lug nut design other than the fact they are not included with the rims and cost is expensive per unit. The tolerances are too tight and after one good outing rust is already forming in the tight lug nut area. Better luck next time STI this for me will be a one hit wonder.

    I have a set of STI HD7 Alloy Matte Black/Radiant Red rims. The lug cavity is too small for the stock Maverick X3 lug nuts that use a 19mm socket. Will these lug nuts work with these rims (with the spline drive nut key)?
    James S on Oct 3, 2017
    BEST ANSWER: Yes, these STI Spline Drive Lug Nuts with the Key will work with your machine. You would just need to make sure you get the 12mm x 1.50mm spline drive lug nut for the Maverick X3.
