Product Emphasis: OEM-quality rear air suspension strut engineered to combine shock absorption with air spring load support, enabling dynamic ride height adjustment and load leveling on vehicles equipped with factory air suspension. This complete assembly includes the air spring bladder and damper unit, providing a direct-fit solution for worn or leaking original components. Designed as a direct replacement for the original strut, which commonly develops air leaks, bladder cracks, or damper wear over time, causing the rear to sag, ride quality to deteriorate, and the air suspension compressor to overwork.

Q1: What does this rear air suspension strut do?
A: It combines a shock absorber with an air spring, supporting the vehicle's weight and allowing dynamic ride height adjustment. The air bladder holds pressurized air while the damper controls spring oscillation. A worn or leaking strut can cause the rear to sag, a bouncy or harsh ride, and the compressor to run constantly.
Q2: Is this a genuine OEM part?
A: 958 358 020 00 is the OEM part number for this rear air suspension strut. It is available as an OEM-quality replacement from brands including Bilstein (45-240287), Arnott, and SACHS.
Q3: What are the symptoms of a failed air suspension strut?
A: Common symptoms include the rear of the vehicle sitting low (especially after overnight parking), a harsh or bouncy ride, the air suspension warning light on the dashboard, and the compressor running more frequently or continuously. Air leaks from the bladder or damaged seals are the most common causes.
