Get stoked on better truck performance with the Bones Hardcore Bushings in Medium, Black/Yellow, 91a from Stoked Ride Shop. These patented Double Action bushings feature a chemically bonded HardCore insert and high-rebound urethane that eliminate the usual break-in period. You get highly responsive turns, better centering and control, and bushings that won’t pop out of their cups—right out of the package. The 91a medium durometer delivers the perfect all-around balance of turn and stability for most riders on street, park, or everyday skating. A complete set includes four cone bushings (enough for two trucks) plus replacement cup washers and fits all major traditional kingpin trucks including Independent, Venture, Thunder, Tensor, and more. At Stoked Ride Shop we focus on gear that gets you stoked—upgrade your trucks and feel the difference on your next session.
Patented Double Action HardCore Design
Bones Hardcore Bushings change how trucks perform. The HardCore insert in the center chemically bonds both sides of the high-rebound urethane cushion together. When you lean, one side compresses as expected while the bonded core prevents the other side from squeezing out and actually increases resistance—so both sides of the bushing work for you at the same time. The result is smoother, more positive turns, improved truck centering, and longer-lasting performance with no stretch-out or floppy feel. Medium 91a hardness is the go-to choice for most skaters, offering responsive turning without sacrificing the stability needed for technical tricks or higher speeds. Install them, adjust your kingpin, and skate immediately.
