Control/Trailing Arm, wheel suspension OEM 31121139991

The 31121139991 is a genuine used OEM control arm (also known as a trailing arm) for the rear wheel suspension. It was originally fitted to several classic BMW and ALPINA models, and this listing refers specifically to the OEM code, not a single physical unit. We source this part from professional dismantlers across Europe, ensuring it is a genuine original equipment component, not an aftermarket copy.

This control arm plays a key role in locating the rear suspension and maintaining proper wheel geometry. It fits a range of BMW 5, 6, 7 and 8 Series models, including the following:

• BMW 5 Series (1981-1984, 1987-1990, and Touring 1991-1996)
• BMW 6 Series (1979-1987)
• BMW 7 Series (1985-1989)
• BMW 8 Series (1990-1994)

Because this is a used part, its exact condition is confirmed per order once we locate a suitable unit from our network. We deliver tracked worldwide, so you can restore your classic BMW or ALPINA with a genuine OEM suspension component. If you are unsure about compatibility, please contact us with your vehicle details before ordering.
