The Kyosho UB014-01 wheel shaft provides a tough replacement option for ULTIMA Series RB7.5 chassis. It is engineered to maintain consistent wheel rotation and reduce drivetrain vibration under race and hobby use.
With careful machining and quality materials, the UB014-01 resists fatigue and keeps power transfer predictable. That stability helps when cornering and when punching out of slow sections on mixed surfaces.
This shaft is compatible with RB7.5 models in the ULTIMA line and swaps in with basic teardown work. Hobbyists can replace the shaft quickly and return to tuning or running sessions.
