We designed our Heavy-Duty Upper Ball joints to be pressed into our arms from the opposite direction placing the load squarely on the joint shoulder rather than the snap ring groove. Made with 4130 studs, ZBROZ has proven over the last decade or more, that improved design means improved strength for you.
