Increase In Local Stress
WARNING: This page is about a different car, the 2019 Ford F-550 Super Duty, 2019 Ford F-450 Super Duty, 2019 Ford F-350 Super Duty, and 2019 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
In any modification of the chassis frame, the addition of holes, reinforcements, welds, clamps or splices may cause an increase in the local stress in the frame at the point of the modification, therefore causing a stress concentration in the frame sidemember(s).
These local stress concentrations can significantly affect the life of the chassis frame. The specific effect which the stress concentrator will have on the life of the chassis frame is influenced by the location of the stress concentration, the frequency and severity of the loading and the magnitude of stress concentration.
