When you turn a normal truck, the central part of the hanger exerts pressure on one side of each bushing (top and bottom). This compresses that side and pushes the other side of each bushing away from the kingpin. We call this a single action bushing because only one side of the bushing is working for you at that time.

The HardCore insert in the center of the BONES Bushings connects the two sides of each bushing by attaching them to the HardCore insert. When the center part of the hanger compresses one side of a HardCore bushing, that side of the bushing reacts like a normal bushing, but the chemical bond between the HardCore and the bushing keeps the bushing from being compressed to the other side. This increases resistance to twisting because it is held in place by the HardCore insert. This basically means that BOTH sides of the BONES HardCore Bushing are resisting your turning force. That's why we call BONES Bushings the first double action truck bushings.
