Detailed Product Description

This Suspensia suspension control arm assembly (X31CJ2549) is specifically designed to meet the suspension requirements of various Mercedes-Benz models such as the C300, C350, CLS450, E300, E350, E400, E450, and E550. Constructed from lightweight aluminum, the control arm provides strength while reducing unsprung weight, contributing to improved handling and ride quality. The corrosion-resistant finish helps protect the component from environmental damage, extending its service life.

The ball joint is pre-greased and features a press-in mounting type with a threaded stud, ensuring a secure and reliable connection to the vehicle’s suspension system.
