A closing assembly for a magneto-rheological damper includes a housing defining a through bore with a first, second, third, fourth, fifth and sixth counter-bores having varied diameters. A wiper seal is disposed in the first counter-bore and an upper seal is disposed in the second counter-bore. A guide is disposed in the fourth counter-bore. The guide and the upper seal and the third counter-bore define a first chamber. A plate defining a passage is disposed axially below the guide in the fifth counter-bore with a flange extending into the sixth counter-bore. A lower seal is disposed in the passage. The guide and the plate and the fifth counter-bore define a second chamber. The first and second chambers separate and contain a lubricating oil adjacent to the upper seal and lower seal.
