When turning a corner or a sharp curve, a vehicle’s body tends to lean away from the direction of the turn and then rebounds. This motion is called roll. Excessive roll may cause a loss of control. With gas charged shocks, roll is reduced.
As tires bounce up and down, road roughness is transmitted to the vehicle’s body and cargo, causing them to vibrate. Excessive vibration may increase a truck’s cost per mile by increasing downtime, reducing tire mileage, reducing vehicle life and lowering resale value. Gas charged shocks control tire motion better than non-gas units, so vibration is reduced.
