  • Publication number: 20260296544
    Abstract: A vehicle includes a chassis including a pair of longitudinal frame rails, a body, a pivot mount pivotally coupling the body to the chassis such that the body is rotatable about an axis of rotation extending laterally, and a spring mount coupling the body to the chassis. The spring mount is positioned longitudinally forward of the axis of rotation and configured to apply a biasing force to resist upward movement of the body relative to the chassis. The spring mount is positioned within 3 feet of a neutral twist axis of the chassis.
