Frequently Asked Questions
Why choose Lemförder over a cheaper aftermarket brand?
Lemförder is an official factory supplier for Mercedes-Benz. While budget aftermarket arms often use inferior rubber that cracks within a year or cheap ball joints that quickly develop play, Lemförder parts deliver genuine 100,000+ mile OEM durability and a perfect, frustration-free fit.
Is this arm for the Driver or Passenger side?
Both! Unique to the GLK-Class platform, this specific lower control arm is non-directional. The exact same part (replacing A2043308011) fits both the Front Left and Front Right sides. (Note: Please add a quantity of two (2) to your cart if you are overhauling the entire front axle).
Does this arm include the bushing and ball joint?
Yes. This is a complete, ready-to-bolt-on assembly. The heavy-duty rubber inner mounting bushing and the outer steering knuckle ball joint are pre-pressed into the aluminum arm at the Lemförder factory.
Will this fit both 4MATIC (AWD) and Base (RWD) models?
Yes. This specific lower control arm design is universally compatible with both the Rear-Wheel Drive and 4MATIC All-Wheel Drive drivetrains found across the GLK-Class lineup.
