Rear Air-to-Coil Conversion

The Unity 30-514200-2-KIT replaces the factory air suspension on the rear axle with a passive coil-spring setup. It is built for owners of rear-wheel-drive Infiniti QX56 models from 2004 to 2010 and Nissan Armada models from 2005 to 2015 who want to eliminate air-system leaks and compressor failures.

Maintenance-Free Operation

The kit removes the air bags, lines and electronic height sensors that commonly fail after years of service. With no compressor to run and no air pressure to maintain, the conversion draws zero electrical power and produces no pump noise during normal driving.

Direct Bolt-In Fitment

Designed specifically for the RWD chassis of the listed vehicles, the kit uses the original mounting points so no fabrication or welding is required. It frees the owner from diagnosing air leaks and replaces the complexity of the factory system with a static spring rate that supports the rated load.

Questions about this item

How do I install the rear conversion kit on my 2004-2010 Infiniti QX56, and what step is commonly missed?

The kit bolts to the factory rear mounts on RWD models only; the step often missed is torquing all bolts to spec after the vehicle settles.

What maintenance will the passive coil springs need after installation?

Inspect springs and mounts at each tyre rotation for corrosion or sag; replace only if ride height drops or noise appears.

What limit appears first during sustained heavy loading on the converted rear suspension?

The fixed-rate steel springs reach their load capacity before the original air bags would, transmitting harsher impacts to the chassis.
