This is a genuine BMW king pin right, part number 31 21 1 095 870. The number stamped on the part is 31211095870; BMW's catalog files it under the short number 1095870. You will find it on our Suspension shelf, under Other Front Axle parts.
It fits the E36 sedan (318i, 320i, 325i and 328i, 1992–1998), with the M42, M43, M50 or M52 engines — and the European-market versions.
BMW draws it on the Front Spring Strut/Shock Absorber (31_0422) diagram.
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
