For hobbyists aiming to tighten up drivetrain feel on TAMIYA TNX or TGM-03 rigs, the JAZRIDER metal shielded ball bearing set provides a simple, effective swap. The 24-piece kit replaces stock plastic bushings to deliver smoother rotation and reduce wear during regular running.
Press each bearing squarely into its bore and confirm smooth rotation before reassembly. Periodic cleaning and a light drop of bearing oil will help maintain performance and extend service life.
