Reinforce your Traxxas TRX-4 with the JAZRIDER JR-TRX423-BK aluminium centre box

Hobbyists looking to reduce failures on rough runs often upgrade the TRX-4 centre gear box to the JAZRIDER JR-TRX423-BK. The black aluminium body improves impact tolerance compared with the original plastic housing.

Benefits of switching to aluminium

Aluminium delivers better resistance to cracks and stress over time. It also keeps gear alignment stable under load, which helps maintain consistent performance in demanding off road situations.

Compatibility and fitting guidance

Designed specifically for the Traxxas TRX-4 family, installation is a straightforward replacement using standard tools. The unit aligns to original mounting points to simplify the swap.

Top features

  • Stronger shell for rough terrain
  • Low weight impact preserves vehicle balance
  • Precision fit for quick installation

Will this improve my crawler reliability?

Yes, replacing the plastic centre box with this aluminium unit reduces the chance of housing damage during heavy impacts and frequent crawling.

Are any extra parts included for install?

The listing covers the aluminium housing itself. Reuse existing bearings and hardware where appropriate, or replace worn items for best results.

Is maintenance different with an aluminium box?

Maintenance is the same: check gears and bearings for wear, clean and relube as needed, and inspect the anodised finish after wet or sandy runs.

Will the black finish scratch easily?

The anodised surface is durable but can show marks from heavy contact; routine care and avoiding unnecessary abrasion will keep it looking good.
