Dinex releases gamechanger OneBox exhaust solution for the American aftermarket

Exhaust and emission manufacturer Dinex releases a unique OneBox exhaust solution used on Freightliner and Western Star trucks for the American aftermarket including a 3-year warranty. The new patented OneBox contains high technology catalysts and particle filters in a quality similar to or better than OE solutions.

Reducing emissions on your existing truck fleet has never been easier with the launch of the new Dinex OneBox – a true game changer on the American aftermarket.


The Dinex OneBox, a two-year long collaboration between Dinex’ OEM and Aftermarket developers, comes with a patented combination of diesel oxidation catalyst, selective catalyst reduction technology and a particle filter – all components of a superior quality superseding existing solution for the OE market. And at a very competitive price.


Thus the Dinex OneBox reduces the need for time-consuming retrofitting of multiple spare parts - paving the way for not only lower emissions but also a better fuel consumption.

“We are thrilled to launch our first complete aftertreatment solution for the American aftermarket. We firmly believe that we are introducing a quite unique product, which also elevating Dinex into a new level as a one-stop-supplier,” says CEO of the Dinex Group, Torben Dinesen.


Dinex is the only supplier in America that can provide all you need from turbo to tailpipe. The full program includes DOC, SCR, DPF, pipes, accessories and sensor program for the heavy-duty vehicles.

Largest aftermarket R&D project ever

With an investment of more than 2 million dollars the OneBox is the largest and most complex aftermarket R&D project ever conducted in the history of Dinex. Comprising 2 years or 5.000 hours to develop, bringing together specialists from both Dinex’ OEM and Aftermarket divisions across multiple countries.


With an investment of 32 tooling’s a dedicated production line in Dublin, Georgia has been installed to assemble the system in the most optimal and efficient way.


The system is structurally designed to match or exceed OE performances, and all manufacturing is done in-house. Dinex has developed an unique patented conecpt for the OneBox as the only one in the aftermarket industry. This feature ensures no OE patents are infringed, a common practice amongst other competitors in the American aftermarket.


“After being a part of Dinex for 30 years, it is a great pleasure to witness the result of such a large scale R&D project for our aftermarket clients. As with our OEM emission systems, the OneBox reduces NOx and other emissions down to a level, where the exhaust air is cleaner than the air we breathe,” says Torben Dinesen.


Field & laboratory tests, Computer aided engineering (CAE) simulations and validations have been done on durability and emission performance to make sure that we have structural and performance stability throughout the entire lifetime of the engine.
