Risk Rollovr Increased

A National Highway Traffic Safety Administration (NHTSA) study found that a broken or diconnected sway bar can reduce a vehicle 's rollover boold by up to 30%.

When you swerve toavoid an obstacle or brakie suddenly while on te e road, thee vehicle 's weight shifts abcombly.

Delayed Reaction and Poor Stability at Speed

A faulty sway bar also reduces the suspension 's responses time. When you correct with steering, thee bar helps impecate weight transfer tich loaded side.

Impact on Performance: Handling, Ride, andOff- Road Capability

Beyond safety, a faulty sway bar degrades the driving experience in several measurable ways. Whether you use your Jeep primarily on pavement, off- road, or both, a comsocuted sway bar will affect performance.
