Frequently Asked Questions
What is the difference between part numbers A2043308311 and A2043308111?
Nothing! Mercedes-Benz frequently updates part numbers across production runs. A2043308311 is simply the updated, fully interchangeable factory revision of the older A2043308111 number.
Why choose Lemförder over a cheaper aftermarket brand?
This specific diagonal tension strut utilizes a complex "hydro-mount" (fluid-filled) inner bushing to dampen heavy braking vibrations. Budget aftermarket brands often replace this with a solid piece of cheap rubber, which ruins the ride quality and fails prematurely. Lemförder provides the genuine fluid-filled design, guaranteeing a perfect, vibration-free luxury ride.
Is this the straight or diagonal lower control arm?
In the GLK's front suspension setup, there are two lower arms. This specific part is the diagonal/forward arm (Tension Strut). If you need the straight/rearward load-bearing arm (Cross Strut), you need part # A2043308011.
Is this for the Driver or Passenger side?
This part number is engineered exclusively for the Front Left side. On Left-Hand Drive (LHD) vehicles (such as in the US, Canada, and mainland Europe), this is the Driver's side.
