ABSTRACT:
A vehicle shock absorber is provided that includes a piston rod. A cylinder head having a bore defining an axis supports the rod within the bore. A scraper is arranged proximate to the cylinder head and includes a hole with the rod arranged within the hole. The scraper removes debris from a portion of the rod exterior of the scraper opposite the cylinder head. Preferably, the scraper is axially located and retained relative to the cylinder head by a retainer. A wiper is at least partially disposed in the hole of the scraper and is in engagement with the rod. The wiper removes water from the rod preventing penetration of the water past the wiper.
