A great upgrade to increase the aesthetics of your board. I am always getting comments on how good the blue anodised hardware looks. I actually didn't even use them on thunder trucks, I used them on the gullwing trucks I have and everything worked sweet except for the pivot cups which were too small but that was expected as the brands didn't match. These are a great idea just to have stashed away or if you want to add a little something special to the look of your board.
