When you turn a normal truck, the hanger web puts pressure on one side of each bushing (top and bottom). This squeezes 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 works for you at a time.
The HardCore insert in the center of BONES bushings connects the two sides of each bushing together by bonding them to the HardCore insert. When the hanger web squeezes one side of a HardCore bushing, that side of the bushing reacts just like a normal bushing, but the chemical bond between the HardCore and the cushion keep the bushing from being squeezed out the other side. It actually increases the resistance to turning because it is held in place by the HardCore insert. This means basically 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.
How to Buy Skateboard Bushings
What skateboard truck bushings do I need?
Skateboard bushings are rubbery-like rings that fit into the skateboard trucks. Each skateboard truck usually has two bushings. The bushings are placed between the baseplate and the hanger and provide the cushion mechanism for turning the skateboard. To be specific, one of the bushings provides the flexibility and turning capabilities of the skateboard truck, while the other allows the trucks to be loosened or tightened depending on your personal preferences. Some riders tend to like their skateboard trucks tight, to better perform ticks. The stiffer the bushings, the more resistant the skateboard is to turning. Other skaters choose to loosen their skateboard trucks for street riding or cruising.
To determine the hardness of the skateboard bushings, we refer to the durometer. Skateboard bushing durometer is usually measured on a Durometer A Scale which goes from 1-100 to measure hardness. Some companies use the B Scale which measures 20 points lower, allowing the scale to be extended by 20 points for harder bushings. So an 80b durometer is the same as 100a durometer.
