These nuts are perfect for my Β½ ton Sierra. They are slightly shorter than the factory lugs, which is better than sticking out further like most of them on the Revain. I originally bought a set of McGard nuts 24215. I wrote a review for this article for you to read, but more often than not the centers break out of them when very little torque is applied. Their design transmits all the torque to the base of the stud, making it almost impossible to break. Your tops spin freely and you must line up the top with the bottom for the wrench to work. This makes it almost impossible to attach a vise to them. If you are looking for a set for a half ton, 1500, Chevrolet Silverado or GMC Sierra these are the best I could find.
