Stiffen up your Traxxas TRX-4 with the JAZRIDER JR-TRX423-BK centre gear box

If you want a more robust centre gear box for your Traxxas TRX-4 Scale and Trail Crawler, the JAZRIDER JR-TRX423-BK in black aluminium is a practical upgrade. Built for everyday trail use, it replaces the stock plastic housing to give better resistance to impacts and long term wear.

Advantages of aluminium housings

Aluminium housings offer a step up in strength without a big weight penalty. Compared with the original plastic component, the JAZRIDER aluminium box handles knocks and repeated stress better, lowering the chance of cracking during hard runs.

Fitment and fitting notes

This centre gear box is made to fit the Traxxas TRX-4 line for an accurate drop-in fit. Basic RC tools are all you need to swap it in, and the design keeps the original geometry so no major chassis changes are required.

Main advantages

  • Greater impact resistance for rough terrain
  • Low added weight to keep handling predictable
  • Engineered fit for straightforward installation
No, the unit is machined to match the TRX-4 centre box dimensions, so driveline alignment remains the same when fitted correctly.
You can transfer the original bearings and seals if they are in good condition, but replacing worn items while installing gives the cleanest result.
The black anodised finish helps resist surface corrosion, but rinse and dry parts after wet use to preserve the finish and internal hardware.
