Our pad drivers come with the appropriate spacer blocks already installed, and with the clutchplate whenever possible. This means that when your order arrives, you just have to take it out of the box, put it on your machine, and you're ready to go, no messing with assembly or centering parts.
These riser blocks and spacers come in handy for re using older and wider brushes or anyplace that the block & clutch plate needs some height for better fitment.
Please feel free to email us if you have a special or unusual application. We've got years of experience and lots of parts to make everything fit and work together.
