Good To Know

Q: Do I need an alignment after installing these control arms? A: Yes, a professional alignment is recommended after any lower control arm replacement. New arms can shift camber and caster settings, so align the front end before regular driving.

Q: Can I install these control arms myself? A: These are a direct-fit replacement pair for compatible Mercedes AWD models. Installation requires suspension tools and a torque spec sheet, so many owners choose a qualified shop.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
