I was hesitant to purchase this product as I have had bad experiences with generic nuts in the past. However, I am extremely impressed with the JENDYK Black X10 DW22B Hub Centric Nut Dual .As my tests showed these nuts provide a secure fit that minimizes vibration and wheel wobble. They are very easy to install and provide an excellent upgrade for anyone who is serious ABOUT automotive performance. The only con is that they are slightly more expensive than some generic alternatives, but the quality more than justifies the price. Overall, highly recommended..
