Rear Roll-Over Strut, BMW - E82 128i/135i, E9X 325i/328i/330i/335i/xi

This is the rear Roll-Over Strut (aka lower Spring Arm) used on the E82 128i/135i and E9X 325i/328i/330i/335i and Xi xDrive models. BMW calls it a Roll-Over Strut but it's everyone else calls it a lower Spring Arm or lower control arm. It's the main arm in the E82/E9X rear suspension, cradling the spring and providing the mounting location for the bottom of the rear shock. The inner mounting bolt is also the factory camber adjustment. A new lower rear shock mount is included (BMW part #33526768544). Inner and outer bushings are sold separately.

This is a Genuine BMW E82/E9X lower spring arm with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.

OEM rubber bushings for this arm are only sold separately. However, Powerflex offers urethane rear toe arm bushings with a lifetime warranty. See below for link and details.
