I got the set of 4 Mopars - 1 per wheel, from the dealer initially and had them installed right then. I don't like them. They have already corroded in the year I've had the truck. Plus they don't look uniform, much larger than the regular nut. The finish on them is sub-par. I plan to switch to a full set of spline nuts but the shops around me don't have the right sizes in stock in black. It's easy to find chrome, though. I'll have to order some I guess. Hasn't been a priority.
