• Complete air spring assembly for faster change-outs
• Alloy piston construction for durable support in heavy-duty service
• Rated for up to 7 bar (100psi) operating pressure
• Designed for broad temperature use from -40°C to +70°C

Compliance and Safety

Support the trailer safely, isolate the air supply, and depressurise the suspension system before removal. Confirm all fasteners seat correctly and torque them to the vehicle manufacturer’s specification. After installation, leak-test the air line and fittings and re-check clearances through full suspension travel.

Trailer Applications

This Freightliner trailer air spring assembly suits on-road trailer air suspension systems where a complete bellows and piston unit is required. It is commonly used in linehaul and general freight trailers that run air ride for load equalisation and payload protection. It can also suit fleets that want consistent ride height to protect tyres, hubs, and chassis components over rough surfaces.

Cross-reference and Suitability

This part cross-references to or suits the following equivalent part numbers and compatible alternatives:

Therefore, confirm piston material and mounting details because similar bellows can be supplied with different pistons for different applications.
