Improved ground clearance

Spring members. Air bellows. Stabilisers. They’ve traditionally sat below the axle, in the line of fire for rocks and stones. Not any more. Our engineers turned the air suspension upside down and placed it on top of the drive axle. The result? You get the ground clearance of leaf suspension with the comfort and efficiency of air suspension.

Better traction, higher average speed

Optimised rear axle pressure on every axle means better traction. And you can adjust the axle load distribution to improve traction further. The air suspension also reduces the amount of vibration in the truck – giving you a more comfortable ride, a higher average speed and increased productivity. Reduced vibration damage boosts your uptime, too.

Stabilisers in bogie centre

Improved stabilisers play an important role in the new air suspension. Turned upside down and located centrally between axles, they convey road and trailer forces into the stiffest part of the frame to improve roll stability.

Axle-mounted air bellows

A new position above the axle means the air bellows are protected, and ground clearance is improved.

Protected brakes

No part of the braking system falls beneath the rear axle, so your truck can manage almost any obstacle.
