Tie rod/turnbuckle and ball ends. Usually bought separate unless for a specific rig, then sometimes they sell them together and purposed for a specific spot. They are made/sold in many sizes/lengths.
I've seen some people call em camber links but I believe generally they are more often called tie rods or the center piece is called a turnbuckle and the ends are called ball ends as Olds said above.
