A hydraulic damper comprising:
- a moveable rod having a centerline axis;
- a collar circumscribing and coupled to the moveable rod;
- and
- a ring axially adjacent the collar, the ring comprising:
- an inner wall extending circumferentially about the centerline axis and circumscribing the moveable rod;
- an outer wall extending circumferentially about the centerline axis, the outer wall circumscribing the inner wall;
- a first wall interconnecting the inner wall and the outer wall at a first end of the ring, the first wall being axially adjacent the collar;
- a second wall, axially spaced from the first wall, interconnecting the inner wall and the outer wall at a second end, axially opposing the first end, of the ring;
- and
- a boss provided along a portion of the first wall and defining a raised portion of the first wall, the boss terminating prior to the inner wall, the boss forming a contact point defining a fluid-tight seal with the collar during a first stroke of the hydraulic damper.
