2 Front Ball Joints with accompanying castle nuts and ball studs. MUST BUY BOTH! Bought in November 2024 and installed in my 2016 Subaru Forester 2.5i but only driven 25mi before realizing I ought to just replace the entire Front Control Arms which come with new ball joints anyway. So they do have slight wear just from installing, then uninstalling. Been sitting in their boxes since then and forgotten about till now. Just hoping to help someone save money on a repair job while recouping some of the cost on my end! This fits other vehicles too but you'd have to reference it yourself by looking it up.
