This high-precision 7-piece bearing kit is a direct factory upgrade designed specifically for the Kyosho Mini-Z MR-04 chassis. Replacing standard plastic bushings or worn factory bearings with this premium set significantly reduces drivetrain friction and rolling resistance. The result is smoother throttle response, higher top-end speeds, and extended battery runtimes on the track.
⚠ Fitment Note
-
MR-04 Dedicated: This kit contains the exact sizes and quantities required specifically for the newer Mini-Z MR-04 chassis platform. Please verify your vehicle manual for compatibility if attempting to use this on older MR-03, AWD, or buggy platforms, as bearing counts and sizes differ.
