So Gorilla is one of the few companies that makes narrow and long M14 x 1.5 nuts. What makes them hard to find is the high mechanical strength that is required. They fit Chevy Trucks, e.g. B. Silverado/Sierra 2500HD to 3500HD Duramax. Pounds per foot and load capacity are the primary factors in the manufacture of these lug nuts. Heck, I can't even find custom colored nuts that have any damn value for this reason. This is my second set because the first set wore out while working under a truck doing minor preventative maintenance. The problem is that my home parking problem, lack of parking after 4pm, forced me to put my bikes back to park on the spot before my wife gets home in her car. This kept the entrance open to them. The fact that the wheels and the age bothered me from time to time, I buy exactly as a replacement. I mean, they've been seriously abused and they're still pretty good looking. So I give them 5 stars for making a quality product that looks good and lasts a long time.
