    Great quality, and it is the same clip style of stock, rather than a solid piece that won't ratchet.

    I recently purchased this cap in RED on my last order to match everything else I've bought here and the picture here on website doesn't do it justice. It looks great sitting on my freshly painted V/C's in VHT Gloss Black. Getcha one, you won't be disappointed. Thanks Riffraff !

    I looked at the ones on ebay they might be a little cheaper but they don't look as good as the riff raff one money well spent

    I ordered the red one & it looks just like the picture! I love it! L99 F250 super duty!

    It seems a bit $ but the quality & style is amazing. If I had a 2nd 7.3 I’d buy another!
