Featuring stainless steel hardware for pinch bolts, and a satin finish. Also, underneath there are 2 tapped holes to add aftermarket gauges, or your factory bracket and clocks. Since these are flat across, when compared to the stock units, they WILL lower your front end about and inch. To some it is not a big deal, but it is also something to be aware of. It will sharpen up your steering, but you will also lose a little ground clearance at the frame center (Less than a half inch).
