20 lugs of number 2/3 and 4 lugs of number 1. If every lug is a true lock you'll have issues with the key quickly. Especially if an impact gun is used.
FYI the new truck should be 14x1.5 now. At least if it's using the same lugs as the 15+ F150's
Good info on the size. I was going off Gen1. I won't order until I can measure them IRL. As for all being locks, I've had them on My Wife's Edge sport for almost 6 years without any issue. I would never use and impact gun on aluminum wheels. I also thinks this speaks to the quality of the product. Gorilla lugs/locks/keys are well made and I've used them for years without any issues. Not even pealing of chrome or paint.
