SDI DU Piston Bushing Conversion Kit 40 mm DRPBK-KYB40 for Yamaha YZ85

DU Piston Bushing Conversion Kit - 40 mm

The SDI DU Piston Bushing Conversion Kit is a 40 mm replacement wear-band solution designed to replace the stock wear band. Its bushing design is intended to lower friction and help provide consistent damping throughout the life of your oil.
