The front suspension has two primary purposes:

The front suspension absorbs the impact of the tires traveling over irregular road surfaces and dissipates this energy throughout the suspension system. This process isolates the vehicle occupants from the road surface. Ride characteristics are designed into the suspension system and are not adjustable.

A heavy-duty shock absorber is used in conjunction with heavy-duty hydraulic bumpers or struts to absorb dissipative energy at the end of the road wheel arm jounce travel. This enhanced system will dampen out the oscillations of the torsion bar spring.
