Upgraded aluminium centre housing for rough runs

Replace the stock centre housing on your Traxxas TRX-4 with the JAZRIDER JR-TRX423-GU aluminium gearbox to get a stronger, more durable core. The gun metal finish gives a low-key scale look while adding protection where you need it most.

Aluminium advantages for off-road use

Aluminium reduces flex and keeps gear alignment steady during heavy crawling and trail abuse. That stability can reduce premature gear wear and keep driveline losses down over extended outings.

Installation and service pointers

Fitting the JAZRIDER unit follows the standard TRX-4 service procedure. Transfer internal components carefully, use the correct lubricants, and verify free rotation before final reassembly.

Specifications

  • Material: Aluminum
  • Finish: Gun Metal
  • Compatibility: Traxxas TRX-4

An effective, lightweight upgrade for Australian-style off-road use where durability and consistent performance matter on long trail days.

Does the JAZRIDER JR-TRX423-GU add a lot of weight?

The aluminium housing adds some mass compared to plastic, but it is modest and improves rigidity. The trade-off favours durability for most off-road setups.

Can I use the existing internals from my TRX-4?

Yes, internals can be transferred. Inspect bearings and seals during the swap and replace any worn parts to avoid future issues.

Are any extra parts needed to fit this gearbox?

In most cases no extra parts are required. Keep original bolts and small components and confirm fitment with your existing TRX-4 chassis layout.
