Nissan Navara NP300 Rear Full-Air

The Nissan Navara NP300 is engineered as a refined daily driver — but load it up, tow a trailer or run it at payload and the rear suspension tells a different story. Coil springs compress under weight, the rear sags, handling is compromised and ride quality deteriorates. For operators using the Navara as a genuine working vehicle, rear sag under load is a daily reality.
 
This rear full-air kit from On Air Suspension replaces the standard coil rear suspension entirely. Air pressure replaces coil spring rate — the system adjusts automatically to maintain near-constant ride height, geometry and handling regardless of load condition. It's a complete rear air suspension upgrade for the NP300 platform, also compatible with the Mercedes-Benz X-Class which shares the same underpinnings.
