Yokomo S4-010B71A Center 71mm Dogbone for YZ-4S  [S4-010B71A]

Rear center dogbone for YZ-4S

This part is a 71mm center dogbone intended for the rear center position on YZ-4S scale RC cars. It serves as a direct replacement for the stock rear center bone and is supplied as a single unit per package.

The component is designed to restore correct driveline length and alignment when replacing worn or damaged dogbones. It fits within the rear center driveline assembly and is intended to be used with the specified compatible chassis only.

Installation notes: verify fitment with the existing cups and axle geometry, inspect retained snap pins or set screws, and confirm rotational freedom before full reassembly. For tuning, replacing a worn center dogbone can reduce play in the driveline and help maintain consistent rear traction response.
