A damper assembly includes a main tube disposed on a center axis and defines a fluid chamber for containing a working fluid. A main piston is disposed in the fluid chamber dividing the fluid chamber into a rebound and a compression chamber. A piston rod is attached to the main piston for moving the main piston between a compression stroke and a rebound stroke. An additional piston is attached to the piston rod adjacent to the main piston. The additional piston includes a body having an upper and a lower member defining a groove. A sealing ring is disposed in the groove and being radially expandable in response to a working fluid pressure. The sealing ring includes at least one annular collar extending outwardly from the sealing ring for forming a locking engagement with the upper and lower members to limit the radial expansion of the sealing ring.
