Product Details

The Arnott eRide Adaptive Ride Control line is built for drivers who want OE-style suspension behavior with modern electronic control. This ASE-5158 air suspension strut uses digital vehicle inputs to adapt damping performance in real time, helping preserve the precise handling expected from the original front suspension setup. It is a direct replacement style solution for Mercedes-Benz S450, S560, S560e, S560L, S450L, S400L, S550, S550e, S500, S500L, and S400 applications listed for the front right position. This part number, ASE-5158, is engineered as a new unit rather than remanufactured, and it cross-references Mercedes-Benz OE numbers 2223202000 and 2223202400 for the same application.

Common Suspension Issues Addressed

• Front right ride height loss or uneven stance
• Excessive bouncing, harshness, or inconsistent damping
• Air spring leakage from a worn bladder or seal area
• Electronic suspension fault codes tied to strut performance
• Noisy or unstable front suspension operation

Installation Notes

Verify the vehicle’s front right application and OE part number before installation. Because this strut uses electronic ride control and air suspension components, proper system diagnosis, calibration, and post-installation checks are important. Inspect related air lines, connectors, and mounting points during replacement to confirm the suspension system is operating correctly.

Quality Assurance

Arnott tests these electronic struts for temperature extremes, road conditions, and repeated compression cycles. The ASE-5158 is a new, USA-manufactured replacement built to meet the demands of active air suspension systems on Mercedes-Benz S-Class vehicles.
