This is the OEM outer tie rod end for the left or right of 1977-1983 E21 320i and 323i models. This is only the outer ball joint that threads onto the tie rod itself. Buying only the outer ball joint will save you time, effort, and expense as you don't have to remove the boot o replace an inner ball joint that does not need to be done.
Note: some models have a manual steering rack with steering damper and this will fit the left and right side tie rods.
This tie rod is manufactured by Lemforder, one of the original suppliers to BMW for tie rods and many other suspension and chassis parts for nearly all BMW models. It comes with a two year warranty.
