Abstract

A cover system for a damper includes an outer tube and a piston rod extending from an end of the outer tube. The cover system also includes a dust tube disposed around a portion of the outer tube. The dust tube includes a first end located proximal to the end of the outer tube and a second end opposite to the first end. The dust tube at least partially encloses the piston rod. The cover system further includes a cap connected to the outer tube. The cap is adapted to at least partially cover the first end of the dust tube.
