Sisu K-AKK-8X4 – Finnish eight-wheel trucks for heavy haulage and timber transport: six- to eight-cylinders of 15.6 to 18.1 litres displacement, 440 to 464 kW, 36.5 to 43.5 t gross weight
Sisu K-AKK-8X4 is a range from the Finnish manufacturer Sisu for heavy trucks with the 8x4 wheel formula, meaning eight wheels of which four are driven. This axle configuration spreads high axle loads over two drive axles and one trailing axle and is the common layout in Finland and Scandinavia for timber-transport and construction vehicles with particularly high payload. Sisu, based in Karis (Karjaa), has built these chassis for decades for Nordic heavy haulage.

The register lists here 6 versions with 440 to 464 kW from six- to eight-cylinders of 15,569 to 18,131 cm³, unladen weights from 14,100 to 17,200 kg, gross weights from 36,500 to 43,500 kg, lengths from 8,650 to 9,939 mm and widths from 2,500 to 2,550 mm.
Eight-wheel trucks with the 8x4 formula are the standard layout for heavy tipper and crane vehicles in the Finnish construction and forestry sector; the wide span of gross weights in this Sisu range shows use both as a bare chassis and as a tractor for trailer combinations.
On used K-AKK-8X4-range trucks, engine operating hours, the condition of both drive axles and the transfer case, rust on the frame and body mounting beams, brake and tyre condition appropriate to the axle load, and on tipper versions the hydraulic system count; spare parts run through the Sisu service network.
