1. About: What Are These Parts?

These part numbers represent the Front Lower Control Arms (Rearward Position / Trailing Arms) with pre-installed rubber bushings and an outer ball joint. Manufactured from lightweight aluminum, they play a critical role in maintaining wheel alignment, stabilizing directional movement, and absorbing road vibrations to ensure a smooth premium ride.

Important Installation Note: BMW utilizes torque-to-yield (stretch) bolts for these control arms. When replacing these arms, it is highly recommended to use brand-new factory-spec hardware, as the original bolts stretch upon initial factory installation and should not be re-used.
