LANDNOVO — Precision in Motion. Engineered by GB.

Is your Jeep Grand Cherokee sitting unevenly at the rear, sagging on the left side, or displaying a suspension warning light? The culprit is often a failed rear air spring. The Landnovo 68258355AC Rear Left Air Spring is a premium, direct OEM-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 left air spring is manufactured to the highest standards, matching the quality of the original Mopar equipment (OE 68258355AC) 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. This genuine OEM Mopar part is engineered to meet or exceed original equipment specifications.

• Ensure the Quadra-Lift air suspension system is properly depressurized before removing the old air spring.
