Description

Overview

Air Spring Assembly for Hendrickson MaxiTraax is a complete air spring and piston assembly used to restore correct ride height and suspension compliance when the existing bellows is leaking, cracked, or fatigued. Replacing a leaking air spring helps keep the trailer level through bumps and cornering and can reduce suspension harshness that contributes to uneven tyre wear.

Features

• Complete air spring assembly for trailer air suspension service
• Plastic piston type for common Hendrickson-style setups
• Supports stable ride height and predictable load control
• Helps prevent air loss caused by bellows cracks or fatigue
