Restore the Solid, Precise Front-End Feel of the Factory
Does your car lean more in corners, or do you hear faint noises from the chassis over bumpy roads? For owners of the Mercedes-Benz C-Class (W205) 4-Matic who care about handling precision and ride quality, the health of the front axle chassis components is the key to the driving experience.
CTE, European chassis technology specialists, has built the Front Axle Chassis Service Kit (Part No. COS21007) specifically for the W205 4-Matic. It brings the core front chassis wear parts together in one kit, saving owners and workshops the hassle of matching part numbers one by one, and restores the solid factory road feel with international-grade manufacturing standards.
