Hey Chris, that is for the full set, two joints per side. So far I have been extremely satisfied with the level of tightness or steering precision that the new ball joints added. I installed the Non-knurled ones because I still had the originals and I knew that the axle cups were undamaged and therefore didn't need the additional "teeth" to bite into the axle. They look very well-made and we'll see how they do. So far, so good but beware, it's a beast installing the set with hand-tools!
