Air suspension

Catalogue of Air Suspension Components for Heavy-Duty Vehicles

Our air suspension section is aimed at transport professionals and workshops that require specific spare parts for the maintenance of truck, bus, and trailer fleets. In this catalogue, you will find a technical selection of components designed to restore load capacity, stability, and driving comfort in industrial vehicles.

The proper replacement of these components is essential to ensure road safety and protect cargo integrity. We offer references compatible with the leading suspension systems on the market, facilitating the repair of common failures such as air leaks or worn air springs, thus optimizing vehicle downtime.

Key aspects when choosing air suspension spare parts

• OEM reference: It is essential to verify the original part number to ensure full compatibility with the vehicle’s system.
• Mounting type: Check whether installation is performed using a metal piston, plastic piston, or if specific mounting plates are required.
• Axle position: Identify whether the replacement part is for the steering axle, drive axle, or a lift axle on a semi-trailer.
• Dimensions and specifications: Review the diameter, maximum/minimum height, and load capacity indicated in the product’s technical data sheet.
• System brand: Ensure the component is compatible with the suspension system manufacturer (e.g., Wabco, Knorr, etc.) or the vehicle manufacturer.

Frequently Asked Questions

How can I identify the correct reference for an air spring?

The most accurate way is to locate the code printed on the old part or consult the vehicle’s technical parts catalogue using the VIN number. If this information is unavailable, it is necessary to compare dimensions and base type with the manufacturer’s specifications.

What symptoms indicate that the air suspension needs repair?

The most evident signs include loss of vehicle height after being parked (air leaks), warning lights illuminated on the dashboard, excessive compressor noise, or unstable driving with excessive bouncing.

Is it necessary to replace suspension bellows in pairs?

Although technically a single unit can be replaced, it is strongly recommended to replace both sides of the same axle simultaneously. This ensures balanced vehicle response and prevents the new part from bearing a disproportionate load due to wear on the old one.

Do the spare parts include valves and mounting accessories?

This depends on the specific reference selected. Some complete kits include the necessary bolts and air valves, while others supply only the air spring or bellows body. We recommend carefully reading each product description before placing your order.
