    Great look

    Black engine spikes look awesome!

    Great quality and definitely gives the bike a cool finished look.

    Well built pretty cool look

    Picked these up to cover the allen head bolts on my 04 Softail. Easy as hell to install, I used a small jewelers mallet to make sure they were all seated properly. The spikes gave my train a finished look, and covered the crappy factory bolts.
    The larger covers don't fit on any of the bolts on my bike period, but oh well, I'm sure I'll find a use for them. When I pick up another bike I'll buy another set for sure!

    They fit and look very nice. Made with knowing how people love making their bike look good and with pride. A must if one rides and likes his/her Iron look nice.
