Through the use of springs, the suspension system
protects the truck's axle from powerful impacts by absorbing the shock of contact with the road.
Without a properly functioning truck suspension system
, either spring leaf or otherwise, you would feel it every time your vehicle crossed any bump or rough patch in the road.
Because the truck suspension lessens the impact of contact with the ground, the system prevents your trucks tires from bouncing off the road as the truck moves along. Without this system in place, or with a malfunctioning system, you would not be able to control the truck.
For this reason, it is important that your truck suspension system is maintained and repaired by professionals.
