FRAME
THE HIGH C-PROFILE FRAME (C460) USED IN THE SISU POLAR IS DUE TO IT´S RIGIDNESS AND BUILDABILITY SUPERIOR TO ALL OTHERS.
The frame of each Sisu Polar is designed and manufactured keeping in mind the purpose of the vehicle. End use specific equipment is integrated into the vehicle frame, thus, forming part of the vehicle body and load-bearing structure. Excess holes in the frame are not required. The result is a strain resistant first-class structure.
Due to its superior fatigue resistant high c-profile frame the Sisu Polar is well-known for excellent tipping stability. The C-460 frame guarantees the best possible driving capabilities.
Recent further development of the frame by altering the radius and added precision to the manufacturing process makes the C460 a first-class frame.
Trucks built based on the high c-profile frame are notably lighter than a low profile reinforced subframe truck.
As an example, a 4-axle Sisu Polar gravel truck built on the C460 frame is hundreds of kilograms lighter than a truck fitted with a subframe.
