Product Details

Arnott SK-3217 is engineered for Mercedes-Benz R-Class SUV owners who need a rear shock absorber for Airmatic-equipped vehicles with Adaptive Damping System hardware. This replacement shock is designed to eliminate the common issues associated with the factory ADS setup by using a tuned valving strategy that delivers consistent damping response. The included coil resistor plugs in to prevent suspension dashboard warning lights after installation. This part cross-references Mercedes-Benz OE numbers 2513200931 and 2513201031 for the same application.

Common Problems This Part Can Address

• Rear shock leakage or loss of damping control
• Excessive bouncing or unstable rear suspension behavior
• Suspension warning lights caused by ADS-related faults
• Noisy rear suspension from worn bump stop or protective boot components
• Ride quality changes caused by a failing adaptive rear shock

Installation Notes

Compatible with rear left or rear right positions on listed Mercedes-Benz R-Class models. Verify that the vehicle has front air suspension and is not an AMG model before ordering. The coil resistor is used to address the electronic warning light issue associated with the original ADS system.

Arnott backs the SK-3217 with a Limited Lifetime Warranty and a 30-Day Satisfaction Guarantee.
