Ditch that old, unsightly look of your upper S10 ball joints by covering them up with a beautiful set of CNC machined billet aluminum Power Performance Covers. These covers are simply held in place by a stainless button head bolt that replaces your existing zerk fitting. Now you will want to hang on to those zerks for future lubrication of the balljoint. It takes only a matter of seconds to take off the cover and install the original zerk fitting. It's a piece of cake!
