LANDNOVO — Precision in Motion. Engineered by GB.

Is your Mercedes-Benz E-Class or CLS-Class sitting unevenly at the front, sagging on the right side, or displaying an AIRMATIC suspension warning light? The culprit is often a failed front air suspension strut. The LANDNOVO 2123234400 Front Right Air Suspension Strut is a premium, direct OE-grade replacement engineered to restore your vehicle's legendary ride comfort and AIRMATIC performance.

The LANDNOVO Difference

LANDNOVO is a premium automotive brand with a distinct British engineering heritage, crafted for discerning drivers who demand nothing but the best for their vehicles. Every LANDNOVO component is Designed by GB — a mark of British precision, quality, and durability.

This front right air suspension strut is manufactured to the highest standards, matching the quality of the original equipment (OE 2123234400 / A2123234400) that came factory-installed on your Mercedes-Benz. It is a complete drop-in replacement, designed for a straightforward installation.

Why Choose the LANDNOVO Air Strut?

The air suspension strut is a critical component of your Mercedes-Benz AIRMATIC suspension system. It combines the damping function of a shock absorber with the load-levelling capability of an air spring, working in coordination with sensors, valves, and the compressor to maintain proper ride height and adjust suspension stiffness. A failing air strut can cause sagging, a rough ride, and put immense strain on the air compressor, potentially leading to costly compressor failure.

Instead of paying dealership prices, the LANDNOVO air strut provides the same OE-level reliability at a fraction of the cost.

Symptoms of a Failing Air Strut

• Front sagging – the right front sits lower than normal, especially after sitting overnight.
• Rough or bouncy ride – loss of cushioning, making the vehicle feel harsh over bumps.
• Air compressor running constantly – the system tries to compensate for leaking air springs.
• Hissing noise – audible air leak from the air strut area.
• AIRMATIC warning light – the dashboard displays a suspension system warning.
• Uneven ride height – the vehicle sits unevenly from side to side.

Installation Tips

• Professional installation is highly recommended for this component.
• Always replace air struts in pairs (both front left and right) to ensure balanced handling and performance. The left side counterpart is 2123234300.
• Before installation, inspect all air lines and fittings for cracks, kinks, or other damage.
• Ensure the AIRMATIC system is properly depressurized before removing the old air strut.
• After installation, the air suspension system should be professionally tested for leaks using diagnostic equipment.
• Inspect related components including the air compressor, valve block, and ride height sensors for wear or damage.
• Always replace the compressor relay when servicing the AIRMATIC system, even if the old relay appears to function – this is a manufacturer specification.
• Make sure after repair that the system is absolutely leak-proof. Any leak compromises the functioning of components such as the suspension compressor.

Important: Air suspension systems operate under high pressure. Professional installation is strongly recommended to ensure proper fitment, safety, and system performance. Before replacing the air strut, verify there are no leaks elsewhere in the system. Any leak compromises the functioning of components such as the suspension compressor.
