What kind of hardware is packaged with the black Rumble Road kit?
To ensure as consistent a look as possible, MHI completes the black Rumble Roadâ„¢ kit with matching black clamps and nuts. In addition, two of the four supplied washers are black. The built-in threaded mounting stem is uncoated metal and is not conducive to powder-coating; the uncoated stem is used to ground the black speakers.
