The Tamiya 51286 - TRF501X Steel Differential Joint is a direct-fit steel replacement for the TRF501X chassis, designed to enhance drivetrain robustness. It uses quality steel to resist deformation and keep the drivetrain stable under load.
The reinforced steel construction helps the joint tolerate higher forces and repeated impacts, so it lasts longer than many standard components and reduces downtime from breakages.
Made to the same interface as the original part, this joint installs into the TRF501X without modification. That makes it an easy upgrade for racers seeking greater mechanical reliability.
