Description

Overview

Hendrickson PRIMAAX Air Spring Assembly supports consistent ride height and load stability on PRIMAAX-equipped trailer suspensions. Replacing a leaking or perished air spring helps reduce chassis roll, harshness, and uneven tyre wear. A sound air spring also helps your suspension maintain alignment and braking behaviour under changing payloads. If your trailer shows slow levelling, audible air loss, or height instability, this assembly is a sensible service replacement.

Features

• Genuine OEM-style air spring assembly for PRIMAAX applications
• Supports stable ride height under variable loads
• Designed for heavy-duty trailer suspension service use
• Helps reduce vibration transfer from suspension movement

Compliance and Safety

Support the vehicle safely and depressurise the air system before removal. Inspect mounts, fasteners, and air lines during replacement so you do not mask a leak from another component. Confirm ride height settings after installation because incorrect height can affect handling and tyre wear. Follow the OEM service method for torque and line routing as well to avoid chafe and premature failure.

Trailer Applications

This assembly commonly suits trailers fitted with Hendrickson PRIMAAX suspension systems in linehaul and general freight roles. It also suits applications where consistent levelling and load support matter across mixed payload cycles. If you run in dusty or high-heat conditions, inspect air lines and fittings at the same time because minor leaks often show up under higher duty.
