Systems and methods for vehicle suspension assemblies

An electrified vehicle, comprising:

• a chassis having a frame member extending longitudinally along a length of the chassis, the frame member configured to support a portion of a load of the electrified vehicle;
• and
• a first suspension assembly coupled with the chassis and a first tractive element, the first suspension assembly comprising:
• a first knuckle coupled with the first tractive element;
• a first strut-damper coupled with the first knuckle and the chassis, the first strut-damper extending between the chassis and the first knuckle, wherein the first strut-damper is a spring-less strut-damper and extends in a direction parallel with a longitudinal axis of the frame member;
• a first control arm coupled with the first knuckle and the frame member;
• a torsion bar coupled with the chassis at a first end of the torsion bar, wherein the torsion bar extends below the frame member and in a direction parallel with the longitudinal axis of the frame member;
• and
• a drop link coupled with the first knuckle and a second end of the torsion bar, wherein the torsion bar extends along an axis that is coaxial with a pivot point of the first control arm, and wherein the torsion bar is configured to supplement the frame member to support a portion of the load of the electrified vehicle.
