A vibration damper for a reciprocating internal combustion engine consisting of a weight rigidly mounted externally on the cylinder head of the engine. The weight, a solid mass of high-density, inert material, has a periphery generally conforming to that of the head, and is mounted thereon by means of the same threaded fasteners used to mount the head on the cylinder. The weight is mounted on the cylinder head in spaced relation thereto to serve also as a cooling air shroud.
