The fixed-length OE suspension arms are bolted to the chassis and axle through rubber bushings to help reduce the transfer of noise into the vehicle. The rubber bushings also absorb torsional forces created by the suspension arms off-road.
Aftermarket suspension arms and bushings that are less flexible will over-stress the chassis and axle mounting brackets and should not be installed. Yet many manufacturers provide these components with their suspension kits to save money.
