Engineered to provide immediate turning precision and reliable center rebound, the Bones Hardcore Bushings Medium (91A) eliminate the traditional break-in period common to stock truck bushings. Built around Bones' patented bonded inner core technology, high-rebound urethane is chemically fused directly to a rigid plastic insert. This internal structure supports the bushing walls under heavy compression, preventing the urethane from squeezing out or tearing while activating resistance on both sides of the bushing during a turn.
The 91A Medium durometer delivers a balanced blend of fluid, deep carves and stable straight-line tracking, making it an ideal upgrade across street, bowl, and transition setups. Because the integrated hard core provides structural rigidity, they typically run without heavy bottom cup washers, reducing overall weight while delivering sharp, predictable response right out of the packaging.
