A rod guide for use in a piston/cylinder monotube shock absorber includes an annular guide body disposed about the piston rod within the shock absorber cylinder. A rod scraper in a top face of the guide body seals grease and oil inside the cylinder and prevents contaminants from entering the cylinder. A one-piece plastic insert, preferably formed of PPA or other rugged thermoplastic resin with a low coefficient of friction, is retained in a bottom face of the guide body. A rod seal on top of the insert, positioned within the guide body, further seals the cylinder against outward migration of shock oil from the cylinder as it slides along the piston rod and provides support for the rod guide, in both the axial and transverse directions, as the insert moves along and relative to the piston rod.
