This 71mm center dogbone is made for the rear centre location on YZ-4S scale RC cars. It acts as a direct replacement for the factory rear centre bone and is supplied as one item in the package.
The component restores proper driveline length and alignment when worn or damaged dogbones are replaced. It installs into the rear centre driveline assembly and is intended for use with the listed compatible chassis only.
Installation notes: check fit against the existing cups and axle geometry, verify snap pins or set screws are correct, and confirm free rotation before completing reassembly. From a setup perspective, replacing a worn centre dogbone can reduce driveline play and help keep rear traction response consistent.
