The THUNDER BUSHING REBUILD KIT – 90A is an all-in-one overhaul pack engineered to fully refresh a pair of worn-out skateboard trucks. Featuring Thunder’s authentic soft-stiffness 90A durometer urethane formula, these red conical bushings provide a highly responsive, quick-turning feel that allows for sharp carving and easy weight-transfer adjustments without requiring excessive force.

Formulated with high-rebound urethane that resists “squish,” the bushings ensure your trucks center quickly and consistently back to a straight line after every deep turn. This factory-assembled pack comes with all the premium hardware needed to swap out old, degraded components, including hardened steel cup washers, replacement nuts, and high-density pivot cups.
