For TRF419 owners performing maintenance or looking for a straightforward upgrade, the 51565 aluminium diff joints are designed to enhance gear differential operation. They help maintain consistent rotation and reduce internal slop.
The aluminium diff joints from Tamiya are produced in lightweight alloy and finished with hard anodizing for a surface that resists abrasion. That combination supports steady movement during competitive use.
This two-piece set matches the original length required by the TRF419 4WD on-road racing chassis. The precise fit simplifies installation and keeps the differential functioning as intended.
