    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

    Posted by INFRNL on Jan 28th 2019

    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.
