Bones Hardcore Bushings, Soft, Black/Blue, 81a
Bones Hardcore Bushings in Soft Black/Blue 81a give skateboarders the loose, easy-turning feel they want without the usual trade-offs of soft urethane. Built with Bones’ patented Double Action design and a chemically bonded HardCore insert, these bushings keep both sides of the cushion engaged during every lean. The high-rebound Bones cushion urethane compresses smoothly, returns to center quickly, and stays seated in the cup so your trucks never feel floppy or inconsistent. There is virtually no break-in period—install them, set your kingpin nut, and skate. The soft 81a durometer is ideal for lighter riders, cruising, carving, bowl, pool, and transition skating where deep, flowing turns matter most. A complete set includes four cone bushings (enough for two trucks) plus replacement cup washers. Fits all major traditional kingpin street trucks including Independent, Venture, Thunder, Tensor, and more. Upgrade your setup at Stoked Ride Shop and experience more responsive trucks right out of the box.
Double Action HardCore Technology
Traditional bushings are single-action: the hanger web compresses only one side of the bushing while the opposite side is simply pushed away from the kingpin. Bones Hardcore Bushings change that equation. A hard core insert is chemically bonded through the center of the high-rebound urethane, linking both sides of the bushing. When you lean, one side still compresses as expected, but the bonded core prevents the other side from squeezing out and actually increases resistance, so both sides work for you at the same time. The result is highly responsive turns, better truck centering, more control, and bushings that refuse to pop out of their cups. You get the easy lean of an 81a soft bushing plus the stability and rebound that usually only come with harder compounds. That combination is why so many skaters choose Bones Hardcore Soft Black/Blue 81a when they want loose trucks that still feel precise and predictable on the street, in the park, or while carving.
