I just installed these on my 2016 GMC Sierra 1500. I'm tired of struggling with OEM two-piece nuts. With use, the outer shell cracks and deforms, after which the nuts begin to get stuck in the socket (not to mention the bad looks). Enough of it! These whole nuts are well priced and exceeded my expectations. Simple hex shape looks and feels premium (no two-piece rattle) like OEM. I installed with an air impact wrench and can't see any damage to the chrome finish. Time will tell if they hold up to corrosion and rust, but they're guaranteed to look better than my falling apart OEM nuts. The 22mm head fits perfectly. Highly recommended!
