Isuzu N75 7.5t Rear Semi-Air Suspension Kit — AKS2092Y
The Isuzu N75 is a 7.5 tonne light commercial truck used across specialist conversion, welfare, refrigerated, tail-lift and fleet applications. At this weight class the variation between unladen and laden ride height is pronounced — standard rear suspension is engineered as a compromise across the full GVW range, and under load the rear drops, stability reduces and ramp angles become increasingly difficult to manage. On Air Suspension's rear semi-air kit removes that compromise.
Supplied by On Air Suspension. Covers Isuzu N75 7.5t 2014 onwards. Twin rear wheel configuration only.
How it works
Air springs are added to assist the existing rear suspension rather than replacing it. Original suspension components are fully retained. No drilling required — the kit uses existing mounting points. You gain precise, adjustable control over rear ride height and load management across the full legal load range.
Benefits
- Load levelling — air springs compensate for increasing payload, maintaining consistent vehicle attitude across the full GVW range
- Increased roll stiffness — greater lateral stability under load, critical for taller body configurations common on heavier N75 variants
- Rear height control — raise or lower the rear on demand to manage loading dock approaches, tail-lift deployment angles, ferry embarkation and steep access points
- Improved ride comfort — air springs absorb road shock and vibration more effectively than standard leaf springs under load
- Reduced wear — consistent suspension loading reduces stress on chassis components, bodywork and any fitted conversion equipment
- Reversible installation — original suspension components retained, nothing permanently modified
Compatibility
