A streamlined belly-line.
At least the truck has one.

Compared to traditional leaf suspension, air suspension offers many benefits. It provides a smoother ride, regardless of the road conditions – saving the truck, the cargo and, most importantly, the driver from additional wear. We offer a rear air suspension especially developed for construction trucks, offers high ground clearance (at least 300 mm) and is tough enough to handle rough terrain.

Now it’s also available for trucks with a driven front axle (4×4, 6×6, 8×6 and 10×6), for the toughest of driving conditions.

Air suspension GRAS-G2 with high ground clearance


Optimised rear axle pressure

Better traction and higher average speed

Optimized rear axle pressure on every axle means better traction, thanks to the air suspension. The driver can adjust axle load distribution for better traction if needed. Air suspension gives less vibration into the truck and you will get a better driving comfort, especially when unloaded. This will also contribute to a higher average speed.

For driven front axle

For the toughest of driving conditions

Until recently, if you had to drive over really rough terrain, you usually had to opt for leaf suspension. But that’s changed now. Our air suspension is now also available for all-wheel-drive configurations (4×4 and 6×6), as well as other trucks with a driven front axle (8×6 and 10×6).

Stabilisers in bogie centre

The position of the stabiliser bar results in less torsion forces on the chassis and better roll and tipping stability. It also contributes to the high ground clearance.

Air bellows above the axle

The air bellows are more protected and their new positions contribute to the high ground clearance. As do all other components.

Air suspension inside the rear tire envelope

Air suspension

Air suspension provides outstanding driving comfort and makes it possible to vary the ground clearance. No parts of the suspension lay outside the rear tyre envelope (with 315/80R22.5 tyres). This makes it easier to adapt the chassis for applications such as asphalt layers or tippers.
