INTRAAX.47399 or INTRAAX47399 is a genuine Hendrickson air suspension, model AAT25K 16RHL77. An air-ride trailer suspension carries the load on air springs and holds the trailer at its set ride height, spreading the load evenly across the axles.
When one is due for service, the usual signs are worn pivot bushings, scuffed or damaged air springs and leaking shock absorbers. A ride height that wanders out of range often traces back to an air spring or the air controls. Call us with your suspension model and we will help confirm proper fit.
