Durable aluminium centre housing for TRX-4

The JAZRIDER JR-TRX423-GU aluminium centre gearbox gives the Traxxas TRX-4 a robust replacement for the factory housing. The gun metal finish is discreet yet hard wearing, suited to frequent trail use and technical crawling.

Why choose an aluminium centre unit

Aluminium improves chassis stiffness and keeps the gear train aligned under load, which can reduce noise and extend component life. It is a common upgrade for those who push their rigs hard.

Practical fitting advice

Installation follows standard TRX-4 procedures. Transfer seals and gears carefully, set correct clearances and use appropriate lubricants to ensure reliable operation after the swap.

Specifications

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

A sensible, scale-friendly upgrade for owners who want a tougher centre housing without complicated modifications.

Is this suitable for competition crawling?

Yes, its increased rigidity and wear resistance make it suitable for competitive use, provided you set up gear mesh and suspension to match the demands of competition courses.

Will the finish affect scale appearance?

The gun metal finish is subtle and helps retain a scale look while offering a tougher surface than painted plastic parts.

How should I maintain the aluminium housing?

Periodically inspect for loose fasteners and check seals during routine servicing. Clean and re-lubricate gears as recommended to keep the unit running smoothly.
