Practical aluminium centre gearbox for everyday trail use

The JAZRIDER JR-TRX423-GU centre gearbox provides a straightforward, durable upgrade for the Traxxas TRX-4. Finished in gun metal, the housing reduces deformation under load and simplifies routine servicing compared with some composite options.

Practical benefits for hobbyists

This aluminium housing keeps gear alignment consistent during long sessions, which reduces wear on pinions and spur gears. Its robust construction suits daily trail use and frequent maintenance cycles.

Service friendly installation tips

Installation follows the standard TRX-4 procedure. Move internal gears and seals into the new housing, ensure correct clearances, and use recommended lubricants. Check seal seating and fastener torque after the first run.

Specifications

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

A no-nonsense upgrade aimed at hobbyists who value durability and straightforward maintenance rather than elaborate performance claims.

What routine checks are recommended after fitting?

After fitting, verify gear mesh, torque settings and seal placement. Run a short break-in session and then recheck everything to ensure no unexpected binding.

Is additional cooling or venting needed?

No special cooling is required for the gearbox itself. Maintain proper motor and ESC cooling as usual and keep lubricant levels appropriate for your driving conditions.

Where to source spare internal parts?

Use official TRX-4 replacement gears, bearings and seals that match your original setup. Keeping spare seals and bearings on hand makes field maintenance quicker and simpler.
