Aluminium rear gear box for TRAX4 trail builds

This aluminium rear gear box set is a 16 piece RC replacement compatible with TRAXXAS TRX4 Trail Crawler rear assemblies, identified by model TRX4013. The components strengthen the rear differential mounts, suspension link anchor points, rear axle link mounts and the rear C hub for authentic trail and crawler setups.

Designed as metal replacement hardware, the kit reduces flex where stock parts allow movement and helps maintain drivetrain alignment during technical crawling. It is supplied as an aftermarket model component and is not for use on actual vehicles.

Installation notes: parts are provided separately for fitting against the corresponding stock pieces; confirm orientation and clearances on your TRX4 Trail Crawler rear assembly before final torquing and keep original fasteners as a guide.

Packing includes

  • Stainless Steel Cap Head Screw 2.5x14 - 4pcs
  • Stainless Steel Flat Head Screw 2.5x10 - 4pcs
  • Stainless Steel Flat Head Screw 2.5x6 - 6pcs

Specifications

  • Item Aluminum rear gear box set, 16 pcs
  • Material Aluminum
  • Model Number TRX4013
  • Compatibility TRAXXAS TRX4 TRAIL CRAWLER

This TRX4013 aluminium rear gear box set is supplied as metal replacement hardware for TRAXXAS TRX4 Trail Crawler rear assemblies to stabilise mounting points and drivetrain alignment for scale crawling. Always double check part fitment and fastener lengths on your chassis before completing installation.

Does this set include all rear mounts?

The kit provides the aluminium replacement pieces listed and the stainless screws shown under Packing includes; review the parts against your rear assembly to see if any additional fasteners are required.

Is any machining required before fitting?

No machining should be necessary for typical TRX4 rear assemblies, but a dry fit is recommended to confirm clearance and alignment prior to final installation.

Will these parts affect steering or handling?

These parts are structural replacements aimed at stabilising mounting points; any change in steering or handling will depend on your overall build and suspension setup rather than the parts alone.

Recommended torque for screws?

Use a conservative torque value to avoid stripping threads in the chassis; tighten progressively and check alignment as you go. If unsure, consult your chassis manual for screw size guidance.
