This part is an RC rear universal bone designed specifically for the YZ-2 family of 2WD off-road cars. The item is listed as Yokomo Z2-010RB and serves as a direct rear driveline replacement where standard rear dogbones are installed.
Operationally, the rear universal bone conveys drive from the differential to the rear hubs and plays a role in driveline feel and rear traction behaviour. Replace worn units with this part when assessing driveline play during setup or maintenance.
Fitting advice: double-check rear driveline length and end engagement before reassembly, confirm clearance through full suspension travel, and set retaining hardware torque according to your chassis manual. This listing supplies a single packaged unit and matches the 60.5mm length shown in the product title.
