Precision turning with patented double-action response for any truck setup. Bones Hardcore Bushings revolutionise truck performance with chemically bonded HardCore inserts that create true double-action resistance—both sides fight turning force equally for instant responsiveness without break-in. Available in Soft (81A) for loose carvy feel, Medium (91A) for balanced street/park control, and Hard (96A) for stiff stability, these USA-made urethane sets (2 per box, 1 per truck) deliver smooth positive turns that stay centred. Superior to standard bushings, they eliminate slop and boost turning precision across all riding styles. HardCore Insert: Patented bonding prevents bushing deformation for consistent response. Three Durometers: Soft 81A (loose), Medium 91A (versatile), Hard 96A (stable). Double Action: Both bushing sides resist equally for immediate truck feedback. No Break-In: Ready-to-ride performance from the first turn. USA Urethane: Premium quality lasts longer than stock bushings. Complete Sets: 2 bushings per box with top washer for proper kingpin pressure.
