Front Left Thrust Arm, OEM - E39 525i/528i/530i

The Thrust Arm, also known as the thrust rod, upper control arm, or tension strut, on your 1997-2003 E39 525i, 528i, 530i as well as the Z8 Roadster is an OEM direct replacement to the original BMW arm. It includes the inner rubber bushing and the outer ball joint for a complete and total replacement. Replaces the thrust arm on the driver's side.

The rubber inner bushing on the original arm naturally wears prematurely, causing sloppy steering, poor tire wear, and jolting or instability during braking. The ball joint in the arm can also become worn and cause bad handling and wear, so we always recommend checking it along with the bushing and lower control arm (wishbone) when diagnosing issues.

NOTE: For even better handling and performance, we recommend Powerflex polyurethane bushings as an upgrade.

This is an OEM thrust arm manufactured by TRW - an original supplier to BMW for this part, as well as many other arms and bushings. As the OEM it meets all of BMW's original design, fitment, and performance requirements and is TUV approved. OEM parts are the best alternative to more expensive Original BMW parts because they are virtually identical without the inflated price tag. This part has a two year warranty.
