Heavy duty aluminium centre for your TRX-4

The JAZRIDER JR-TRX423-GU aluminium centre gearbox gives the Traxxas TRX-4 a tougher core. Finished in gun metal, it replaces the weaker factory housing to withstand repeated hits and long boggy runs without adding unnecessary weight.

Why aluminium helps on rough terrain

Aluminium resists deformation better than many plastics used in stock housings, so gears maintain mesh under load. That makes a noticeable difference when crawling over rocks or negotiating steep climbs.

Quick installation overview

Swapping in the JAZRIDER aluminium unit is a straightforward shop job. Keep fasteners torqued to spec, use fresh lubricant during reassembly, and check for binding before taking the truck out.

Specifications

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

A no-nonsense upgrade for trail riders who prefer reliability and consistent performance from their TRX-4 without complex modifications.

Is the JAZRIDER JR-TRX423-GU ready to bolt in?

Yes, it is machined to fit TRX-4 centre mounting points. You will still need to transfer seals and gears from your existing unit and apply lubricant as part of the fit.

Will the gun metal finish show scratches easily?

The gun metal surface is durable but will show wear like any metal part. Light scuffs are normal with heavy use and do not affect performance.

Any special break-in required?

Run a few short, light sessions and recheck gear mesh and fastener tightness. This helps confirm correct alignment and lubricant distribution before hard use.
