Used Truck Air Ride Suspension Parts – Air Springs, ECAS Valves & Height Sensors

Used truck air ride suspension parts for European HGVs

Air ride suspension systems use air springs (air bags), valves and electronic controls instead of, or together with, traditional leaf springs. On modern European heavy trucks this helps to improve ride comfort, protect cargo, keep ride height stable under load and adjust chassis height for docks and coupling. A typical system includes air springs on the axles, ECAS solenoid valves and height sensors that control the air pressure in each circuit.

In this category we offer used OEM air ride suspension parts removed from complete donor vehicles. Typical examples include rear axle air springs for MAN TGX/TGS, lift and tag axle airbags for Volvo FH/FM, DAF rear axle air bags, Wabco ECAS solenoid valves and height sensors, together with brackets and clamp plates for mounting the springs on the axle and chassis.

What you will find in the Air Ride Suspension category

Stock in the Air Ride Suspension category changes as new donor trucks arrive, but it typically includes:

• drive, tag and lift axle air springs (air bags) for tractors and rigids with rear air suspension;
• lift / tag axle airbags for pusher and tag axles on 6x2 and 8x2 configurations;
• air spring brackets and clamp plates for mounting the air bags to the axle and chassis;
• ECAS solenoid valves that control air flow to each circuit of the suspension;
• air suspension ride height sensors used by ECAS systems to maintain correct chassis height;
• selected associated fittings such as fixings, supports and small hardware supplied together with the main component, as shown in the product photos.

Each listing includes clear photos, OE/OEM part numbers where available and donor vehicle details so you can compare port positions, mounting pattern, connector type and air spring dimensions with the parts fitted to your own truck.

Truck brands & typical applications

Most air suspension parts in this category are taken from mainstream European heavy trucks, including:

• DAF XF and CF tractors and rigids with rear and tag axle air suspension;
• MAN TGS and TGX long-haul, distribution and construction trucks with rear air suspension and lift axles;
• Mercedes-Benz Actros, Antos and Arocs with air suspension on drive and tag axles;
• Volvo FH and FM long-distance and regional haulage vehicles with rear and pusher/tag axle air bags;
• other brands such as Scania, Iveco and Renault Trucks when suitable donor vehicles are available.

Because these are genuine OEM components removed from complete trucks, each air spring, ECAS valve or height sensor is normally matched to a specific axle configuration, suspension type, ride height and emission standard.

Why air ride suspension matters on a truck

A correctly functioning air suspension system is important for:

• ride comfort and driver fatigue – air springs reduce vibration and harshness in the cab and chassis, especially on long-haul routes;
• cargo protection – smoother suspension movement helps protect sensitive goods from shocks and impacts during transport;
• stability and safety – proper height control and even load distribution improve braking, cornering and traction;
• protecting the chassis and body – maintaining correct ride height and damping reduces stress on frame rails, body mounts and other suspension components;
• flexibility – lift/tag axles and adjustable ride height help optimise traction, tyre wear and access to loading bays.

Typical reasons to replace air suspension components

Common reasons to order parts from the Air Ride Suspension category include:

• leaking or cracked air bags causing continuous compressor operation, uneven height or a sagging axle;
• visible damage or corrosion on air spring bellows, top and bottom plates or brackets;
• ECAS fault codes on the dashboard related to failed solenoid valves or height sensors;
• uneven ride height between left and right side or between axles due to control or sensor issues;
• impact damage to lift/tag axle air bags or brackets after road obstacles or loading incidents;
• replacing non-original or universal parts with the correct OEM air suspension components specified for your truck.

How to choose the correct air ride suspension part

To minimise fitting issues and ensure the right performance, please check the following details before ordering:

• truck brand, model and chassis type – for example DAF XF106, MAN TGX Euro 6, Mercedes Actros MP4, Volvo FH4;
• axle position and function – drive axle, tag axle, midlift or pusher lift axle, single vs twin bags per side;
• air spring design and size – diameter, height range, type of top and bottom plates and stud/bolt pattern;
• air connection details – thread size, position and orientation of the air inlet/outlet;
• electrical connector type on ECAS valves and sensors, number of pins and plug shape;
• suspension and axle codes from the vehicle plate or manufacturer documentation where available;
• OEM part numbers stamped or printed on your existing air bag, bracket, valve or sensor, matched against the references shown in the product description.

If you are unsure, you can contact us with your VIN or registration number and clear photos of the existing air suspension components and mounting area. Our team can help you confirm compatibility before you place an order. For general guidance, see How to Find the Right Part and Compatibility & VIN Policy.

Used OEM air suspension parts from dismantled trucks

VRA Truckparts specialises in used OEM truck parts sourced from carefully selected donor vehicles. Trucks are inspected and documented before dismantling so that suspension, steering and chassis components can be assessed properly. During dismantling, our technicians remove air springs, brackets, ECAS valves and height sensors, check housings and connectors for visible damage and reject units that do not meet our standards.

Usable parts are cleaned externally, labelled with OEM references where available and stored under cover in our warehouse and yard ready for dispatch. To learn more about how we work, please visit Our Dismantling & Quality Process, Warranty & Part Condition and Trucks We Dismantle.
