What It Helps Address

• Rear shock leakage or loss of damping control
• Excessive bouncing, harshness, or unstable rear ride behavior
• Suspension dashboard warning lights related to ADS removal or failure
• Wear in the rear shock mounts, bump stop, or dust protection components
• Need for a replacement rear shock on Mercedes-Benz E-Class or CLS models

Installation Notes and Tips

Verify rear fitment by year, model, and suspension configuration before installation. This shock is listed for the rear position and is used on vehicles equipped with air suspension where noted in the fitment data. The included coil resistor is intended to address warning lights associated with the ADS system after replacement. Confirm left or right side placement at the vehicle level, since this shock is listed for either rear side.

Quality Assurance

Arnott’s New product line focuses on replacement suspension components built for specific vehicle applications. SK-3059 is assembled in the USA and uses new service parts throughout the shock assembly for a complete rear suspension repair on the listed Mercedes-Benz models.
