Engineered to be reliable and durable

With Croner we have created a reliable and durable truck, built with proven robust components without compromising on quality. It’s an enduring and easily serviced truck, so you'll spend less time on maintenance and more time making money on the road. Each component is the result of years of development and harsh stress testing to create the ultimate medium-duty platform.

Reliability and durability testing

Strong endurance has been a UD Trucks trademark since the start of our foundation, which is why our reliability and durability testing programs are so rigorous. Croner has excelled in all of them. 


Durability testing was conducted over an equivalent of 3 million kilometres, putting the Croner to the test in the toughest weather conditions and terrains around the world. In addition, 1.4 million kilometres of field tests in actual customer operations were carried out across 6 countries and 3 continents over a period of 18 months.


    “This truck, and UD trucks in general, handle the extreme conditions here very well. The weather is extremely hot, yet we never had any issue with the engine over-heating. During the testing, this truck proved very helpful for our business. Croner consumes less fuel and also emits less harmful emissions. Our driver is very happy with the performance of the A/C. Croner is safe, reliable, and always offers a smooth drive – we are definitely planning on buying Croner or similar UD models in the future.”

    UD Genuine Parts

    UD Genuine Parts are manufactured to the highest quality and durability standards and are a genuine long-term cost saver. 

    UD Genuine Parts have many important benefits:

    •  12 month warranty, doubled to 24 months, if that part is fitted in an authorised UD Trucks workshop
    •  Designed and tested to last for optimal service intervals
    •  Fit for purpose for your UD Truck
    •  Reduced overall cost per kilometre

    Axle capacity

    The Croner’s high axle carrying capacity delivers more uptime and productivity in heavy load use, such as construction.


    This high axle capacity delivers the ultimate reliability and durability expected of a UD truck.


    A full air braking system with reliable S-cam type drum brakes is offered on all variants. Croner has large capacity brake drum and linings, providing better stopping power and lasting longer between service intervals. Less need for maintenance and replacing parts means boosted uptime, hence saving lifetime costs.

    Front and rear suspension

    Croner offers two reliable and durable rear suspension options, a choice between leaf spring or air suspension. The rear multi-leaf spring suspension comes with a high level of stiffness and strength. The air suspension option is designed to meet customer demand for transport quality of sensitive freight.

    Longer service intervals

    Long maintenance intervals on lubricants for engine, transmission and drive axle. Oil-bath type front axle hub, automatic transmission and large capacity brakes will reduce the lifetime maintenance costs.

    Easy maintenance and repair

    Croner has been designed with reliability and productivity in focus, paired with easily accessible components to minimize the time spent on maintenance.

    • The cab tilts up to 48 degrees, allowing for simpler access to the engine.

    • For daily inspections and maintenance, many of the key checks can be easily performed by accessing the front lid.

    • Full air brake system – without any hydraulics – means no need for hydraulic oil replacement and wheel cylinder maintenance.
