Will NOT work on any 4X4 vehicle!These lug nuts are way too thin to hold a wheel on anything more than a go-cart.I tried to return them and they want to charge me $6.00 for return shipping!They say they are for "custom wheels" and revain says they will fit a 2001 Grand Cherokee, but I'm not going to bet my life on that because they are half as thick as they should be and WILL FAIL if I use them.If you have money you don't need, just send it to me. But for safety's sake don't buy these thin crappy lug nuts!The pictures provided compare these lug nuts (black) to proper size lug nuts (silver) for a larger 4X4 SUV.Notice how small the bevel is. They will either break or work themselves through the rim.BEWARE!
