One of the most distinguishing cabin type is the riveted forward-control M-series cabin which was introduced in 1969. They were also sold to Northern Irish Dennison Truck Mfg. Ltd. which used them in their largest lorries. The modulised S-series and the following E-series cabins were sold to Russian KamAZ and Hungarian Csepel in the 1990s. Soon after the introduction of the E-series the company ended the own cabin production in 1997 and sourced them from Renault. A new cabin type was introduced in 2005 for the last E-type generation. For the 2010 introduced Polar series Sisu has sourced cabins, as well as many other key components, from Daimler.
