We offer rear heavy-duty steel trailing arms for the BMW E9X and E8X series. The product was created to replace the original control arms, the poor structure of which causes them to bend. It is especially noticeable in curves where the wishbones are subjected to high forces that cause them to twist. They will work both in motorsport, but also in the cars we use every day. 

OE Part NO. (BMW): 33322406291 

Our product is made in Poland by qualified people. The swingarm is made of 2mm S355 sheet metal and cut on a CNC punching machine with additional reinforcement, which gives additional rigidity to the swingarm structure. Then they are welded using the TIG method and, in the last stage, powder coated in black. 

The price is for a set, i.e. 2 pcs.
