Bones Hardcore Bushings, Soft, White/Blue, 81a

Bones Hardcore Bushings deliver unmatched responsiveness and control for skateboarders seeking quick, positive turns without flop or rigidity. These medium 91a bushings feature a patented double-action design with a chemically bonded HardCore insert that connects both sides of each bushing, providing superior centering, high rebound, and immediate performance right out of the box. Perfect for street, park, or cruising, they enhance truck performance for smoother carving and better overall skating feel. Double Action HardCore Technology Unlike traditional single-action bushings that only utilize one side during turns, Bones Hardcore Bushings use their innovative bonded core to make both sides resist turning forces simultaneously. This results in highly responsive handling, no break-in period, and consistent performance that prevents the bushing from being squeezed out. Skaters experience increased truck stability, precise control, and the ability to skate anything with confidence.
