I have a 2015 Silverado 1500 LT with 20" OEM wheels. The lock nut kit is longer than the OEM nuts. It looks weird because they protrude a bit more than the OEM protrusions. They also fit within the wheel stud hole diameter and do not protrude outward like OEM tabs to attach the rim to the axle with external force. I suspect tightening it will do something because it is the exact diameter of the wheel stud hole. Although I've looked for the right product in many different places, they all say this is the recommended product for the car. I really do not know it.
