Trailer Air Spring for Hendrickson INTRAAX

Overview

MAXUS Air Spring Suit Hendrickson INTRAAX restores ride height and ride support in trailer air suspension when a leaking or fatigued air bag starts to sag. A sound air spring helps keep the axle group stable under load, which can reduce harsh vibration through the chassis. Because this part replaces the complete air spring unit, it is suited to scheduled suspension servicing instead of chasing intermittent leaks.

Features

This air spring supports consistent ride height so the suspension can work as intended. Replacing a worn air bag early can also help reduce uneven tyre wear linked to incorrect ride height.

• Direct replacement style air spring for Hendrickson INTRAAX applications
• Helps reduce vibration transmitted through the trailer chassis
• Supports stable load sharing across the axle group
• Designed for routine service replacement and maintenance

Compliance and Safety

Depressurise the air system and support the trailer safely before removal. Inspect air lines, fittings, and mounting plates during installation so you do not trap debris or pinch an air line. After fitting, perform a leak check with soapy water, then re-check fasteners after an initial road test. If you are unsure about torque settings or clearance requirements, follow Hendrickson service guidance for your suspension model.
