Awesome colors
I got a Red and a blue for each of my trucks. I can't believe how deep and rich the color is on these. Great piece of american made billet aluminum and I am proud to have it on my power stroke.

Nice Addition
ordered to replace my worn oem cap and to match my RiffRaff billet degas cap.
I think I would have preferred just the RR logo rather than words printed, but not a big deal. They are still great either way.
These utilize the oem cap adding a nice billet shell. Great item if you want to add some color to the engine compartment -
Compliments fuel bowl cap
Now while it is just a machined cover for a stock oil cap it compliments the fuel bowl cap quite nicely

Really great machining and the blue anodizing looks great. Easy install, no leaks. I recommend them to anyone with an OBS truck.
