Suspension

Range of suspension components for heavy-duty and commercial vehicles

The suspension system is a critical element for the active safety and operability of trucks, buses, and industrial vehicles. Its function goes beyond driver comfort, being essential to ensure load stability, tire grip on the asphalt, and the reduction of vibrations that can affect the chassis and the transported goods.

In this section you will find technical spare parts designed to withstand the high demands of professional transport. From shock absorbers and leaf springs to components for pneumatic systems, our range covers preventive and corrective maintenance needs, helping your fleet remain operational and comply with current road safety regulations.

Criteria for selecting the right suspension replacement part

• OEM reference: Always check the original part reference number or the VIN to ensure full technical compatibility.
• System type: Confirm whether your vehicle uses mechanical suspension (leaf springs) or pneumatic suspension (air springs and diapress), as the components are not interchangeable.
• Axle position: Replacement parts vary significantly depending on whether they are installed on the steering axle, drive axle, or trailer axles.
• Load capacity: Make sure the selected component supports the maximum authorized tonnage for your specific heavy-duty vehicle model.
• Peripheral elements: When replacing structural parts, it is advisable to check the condition of silentblocks, bushings, and mounting brackets.

Frequently asked questions

What are the symptoms of worn suspension on a truck?

The most obvious signs include uneven or premature tire wear, excessive cab or trailer lean in corners, unusual vibrations in the steering wheel, and metallic noises when driving over bumps. A loss of ride height may also be noticeable if it is an air suspension system.

What maintenance do suspension leaf springs require?

Leaf springs require periodic visual inspections to detect cracks, broken leaves, or deformations. It is important to check the tightening torque of the U-bolts and the condition of bolts and bushings, as play at these points can accelerate the deterioration of the assembly.

Is it necessary to replace shock absorbers in pairs?

Yes, it is standard practice in professional mechanics. Replacing the shock absorbers on both sides of the same axle at the same time ensures balanced vehicle behavior, preventing braking instability and ensuring even tire wear.

How do air springs affect driving?

Air springs or air bags in an air suspension system absorb road irregularities through compressed air. Their good condition is vital to maintain a constant ride height regardless of load and to protect fragile goods by significantly reducing impacts during the journey.
