Chassis made for the tough conditions.

The new Volvo FMX is developed for one purpose only – to be the best and most suitable truck for construction assignments. That's why we've created the chassis and wheel suspensions that really can cope with the tough conditions in the gravel pit. Here are some highlights.

Chassis heights, approx

  • High: 1000 mm
  • X-High: 1200 mm
  • XX-High: 1240 mm


  • Tractor: 3,000 to 3,600 mm
  • Rigid: 3,200 to 5,600 mm

Volvo FMX rear air suspension

Rear air suspension.

The rear air suspension is specifically developed for construction assignments. It makes it possible to adjust the axle load distribution. It gives minimum vibrations to the truck, contributing to higher average speed without jeopardising the truck.

Volvo FMX new driven front axle

All-wheel drive.

If you want to be sure to get out of the dirt, the 6x6 configuration is the choice.

The new driven front axle has the same position as the non-driven axle, 100 mm further forward, which means that the approach angle is really practical and useful.

Flexible chassis layout

Volvo FMX tractor chassis layout

1. Battery box (BBOX-L)
It is moved forward 300 mm compared with previous design. On tractors this offers 100–120 litres more fuel capacity.

2. AdBlue tank
On tractors a 64, 90, 150 or 190 litre AdBlue tank can be mounted on side of frame or under frame, offering more fuel capacity.

3. APM
The Air Production Modulator (APM) is on tractors placed between the chassis frames in order to create more space for chassis-mounted equipment such as fuel tanks.

4. Free frame space
The chassis packaging can be moved rearwards to create space for crane legs or other equipment. (FAA10; approx. 500 mm), (FAA20; approx. 600 mm).

5. Frame body builder hole row
The upper hole-row is reserved for the body builder. All brackets in upper hole-row have an offset and an 8 mm spacer. No rivets are used in the upper hole-row.

6. Rear air suspension and short rear end
The rear overhang can be shorter thanks to a redesigned forward-mounted stabiliser bar.  This is a benefit for construction applications and improves the asphalt-layer interface and swapbody applications.
