Bones Hardcore Bushings Soft (White/Blue)
With BONES Bushings™, you will notice a number of positive improvements in the performance of your trucks. There is no break-in period. Just put them in, adjust and skate.
3 Hardnesses: Hard Bushing: 96A, Medium Bushing: 91A, Soft Bushing: 81A
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.
