Abstract
A shock absorber has a pressure tube, a reserve tube, a piston rod and a rod guide. The rod guide is located between the pressure tube, the reserve tube and the piston rod. A sealing system is located between the rod guide and the piston rod. The sealing system is held in place by the reserve tube. The sealing system includes a positioning ring, a damper seal and a dirt wiper. The positioning ring locates the sealing system with respect to the rod guide. The damper seal engages the positioning ring and has two sealing lips that engage the rod guide. The dirt wiper engages the damper seal and includes a lip which engages the piston rod.
