Strengthen TRF419 driveline with an aluminum differential case

The Tamiya 42325 - 37T Aluminum Gear Differential Case is a straightforward upgrade for owners of TRF419, TRF418, or TA07 PRO chassis who want a more rigid diff housing. Machined aluminum helps resist deformation and aids heat transfer, reducing the chance of internal oil overheating and supporting smoother, more consistent handling on race days.

Aluminum differential case highlights

  • Material: High quality aluminum construction for extra stiffness and better thermal behaviour.
  • Compatibility: Made to fit TRF419, TRF418 and TA07 PRO chassis layouts.
  • Components Included: Supplied with the 37T aluminum gear differential case, a gasket and four 2x6mm hex screws.
The case is designed for TRF419, TRF418 and TA07 PRO dimensions, so it installs using the standard differential mounting points and included hardware in most builds.
The harder shell does not alter internal gear geometry, but improved heat control can help the diff oil stay within expected viscosity, which keeps tuning more consistent during long runs.
