Perfect for my 2005 Tundra Double Cab. I cleaned the factory studs with no problem. These are true hub oriented spacers which are the only safe spacers that can be used. Spacers have gotten a bad rap due to abuse and installation. My only concern is the poor quality of their anodizing. Most of it is good, but some spots are very thin. Can't complain much about the price, less than half of the well-known brands that are always recommended on the forums.
