Description

Overview

Air Spring Assembly Hendrickson INTRAAX 6.5in to 7.5in supports stable ride height and axle load sharing on Hendrickson trailer suspensions. Replacing a leaking or fatigued air spring helps reduce harshness, improve levelling consistency, and limit uneven tyre wear. It also helps reduce shock transfer through the chassis when the suspension is operating within its intended range.

Features

• Designed to suit Hendrickson INTRAAX 6.5in and 7.5in ride height configurations
• Supports consistent ride height when the system is correctly set and maintained
• Suited to heavy trailer operating environments across wide temperature ranges
• Helps reduce vibration transfer when shocks and bushes are serviceable

Compliance and Safety

Depressurise the air system and support the trailer safely before removal. Inspect air lines for chafe, confirm mounting faces are clean, and torque fasteners to the suspension maker’s requirements. Check that the air spring clears brackets and airlines through full suspension travel, and replace worn shocks or bushes so the new air spring is not forced to absorb uncontrolled movement.

Trailer Applications

This assembly is commonly used on heavy trailers fitted with Hendrickson INTRAAX suspension where stable ride height is critical, including:

• Linehaul and general freight trailers
• Drop deck and tautliner applications
• Tipper and bulk haulage trailers
• Fleet maintenance replacements for INTRAAX-equipped suspensions
