Heavy-Duty Opticruise gearbox

G33 heavy duty gearbox

World-leading off-road fuel economy

The heavy-duty Opticruise gearbox brings world-leading fuel economy to the off-road. Optimised for demanding operations with high GTW, the heavy-duty Opticruise range is engineered to give you the ultimate control and drivability in the toughest terrains.


Complemented by the groundbreaking Scania Super powertrain, it means that 8% fuel savings can now be achieved on the off-road.

More efficient

The new Opticruise is our quietest, lightest, and most efficient gearbox yet. This is delivered through a new aluminium-based compact geometric design, as well as improved oil flow distribution to reduce internal losses by 50%. 

More productive

Supporting higher output torque, faster axle gearing and seamless startability with heavier payloads, the Opticruise is engineered to perform in the toughest challenges. Its enhanced robustness and extended service life will keep your operations rolling long beyond tomorrow.

More performant

Through a wider 14-gear ratio, including a lower ‘super crawler’ gear and up to 8 additional reverse gears, you can enjoy the ultimate control and comfort in even the hardest conditions. This is complemented by improved auxiliary braking and smoother, faster gear shifting.

Take a closer look

Engineered using wider planetary gears and weighing just 5 kilograms heavier than the standard version, the heavy-duty G25 and G33 Opticruise delivers performance you can depend upon in hard conditions with high payloads.

Low-emission performance you can rely on in the next decade

Beyond world-leading fuel efficiency and performance, the new heavy-duty gearbox is a crucial step in enabling the emissions-reductions demanded by off-road industries in the next decade.
