LANDNOVO — Precision in Motion. Engineered by GB.

Is your Jeep Grand Cherokee sitting unevenly at the rear, sagging on one side, or displaying a suspension warning light? The culprit is often a failed rear air spring. The Landnovo 68029912AE Rear Air Spring is a premium, direct OE-grade replacement engineered to restore your vehicle's legendary off-road capability and Quadra-Lift load-levelling 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 rear air spring is manufactured to the highest standards, matching the quality of the original equipment (OE 68029912AE) that came factory-installed on your Jeep Grand Cherokee. It is a complete drop-in replacement, designed for a straightforward installation.

Why Choose the Landnovo Air Spring?

The air spring is a critical component of your Grand Cherokee's Quadra-Lift air suspension system. It works in coordination with sensors, valves, and the compressor to maintain proper ride height regardless of load. A failing air spring 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 spring provides the same OE-level reliability at a fraction of the cost.

Symptoms of a Failing Air Spring

• Rear sagging – one corner, one side, or the whole rear sits lower than normal.
• 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 spring area.
• Suspension warning light – the dashboard displays a suspension system warning.

Installation Tips

• Professional installation is highly recommended for this component.
• Always replace air springs in pairs (both rear left and right) to ensure balanced handling and performance.
• Before installation, inspect all air lines and fittings for cracks, kinks, or other damage.
• Ensure the Quadra-Lift air suspension system is properly depressurized before removing the old air spring.
• 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.

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 spring, verify there are no leaks elsewhere in the system. Any leak compromises the functioning of components such as the suspension compressor.
