Sisu LP-138 – the collective page of the Finnish Sisu truck type in the register: six-cylinder diesel of 4,180 to 6,600 cm³, 110 to 116 kW, gross weights of 14 to 15 tonnes
This page gathers the Sisu LP-138 – medium-heavy trucks from the Finnish maker Sisu of Karis (Karjaa) in southern Finland. The type designation LP-138 follows the maker's own system of range code and number; the individual model names with suffixes such as BIT, CIT or CVT denote different cab and drivetrain versions of the same base type.

The register lists here 5 versions with 110 to 116 kW from six-cylinders of 4,180 to 6,600 cm³, unladen weights from 5,800 to 7,960 kg, gross weights from 14,000 to 15,000 kg, lengths from 6,850 to 8,650 mm and widths from 2,450 to 2,500 mm.
With a gross weight of around 14 to 15 tonnes, the LP-138 belongs to the mid-range of construction-site and distribution vehicles, used in Finland's construction and municipal sector as well as forestry for flatbed, tipper or loader-crane bodies. With types like this, Sisu served the niche between light distribution trucks and the big long-haul machines, favoured by operators who needed a chassis able to cope with unsurfaced roads and Nordic winters.
On a used example, the condition and mileage of the six-cylinder diesel, wear on clutch and gearbox, the condition of frame and body, and corrosion on cab and mudguards all matter. Drivetrain and chassis parts run through the Finnish Sisu service network, body parts through the respective body builders.
