Genuine River Hobby replacement for the VRX MC31 crawler — the outer half of the central CVD driveshaft, the telescoping shaft that carries drive from the transmission to the axle. Centre shafts on a crawler live a twisting life: full suspension articulation works the joint and splines constantly, and when the joint develops slop or the splines wear, drive gets notchy and noisy. This is the half that renews it.

Fitment

For the River Hobby / VRX MC31 crawler (vehicle RH-1050). The MC31's parts also appear under VRX Racing branding — same manufacturer, same part, as the twin-logo packaging shows. Check your manual's exploded view to confirm RH-13009 is the half you need; the centre shaft's two halves are separate part numbers.
