Bones - Black Soft 81A Bushings

These Bones Black Soft 81A Bushings boast a patented Double Action bushing and a chemically bonded core insert, resulting in high rebound urethane that requires no break in period. With highly responsive turns and increased truck performance, these bushings enhance the overall skating experience.

When a truck is turned, the hanger web exerts pressure on both the top and bottom of each bushing. This compresses one side and simultaneously pushes the other side away from the kingpin, creating a "single action" bushing.

The HardCore insert in the center of BONES bushings is designed to bond the two sides of each bushing together. When the hanger web applies pressure to one side, the chemical bond between the HardCore and the cushion prevents the bushing from being squeezed out the other side. This increases resistance to turning as both sides of the BONES HardCore Bushing work against your turning force. This feature makes BONES Bushings the first double action truck bushings.

Hardness: 81A
