Precision aluminium rear gear box for TRX4

This CNC-friendly aluminium rear gear box assembly is engineered for the TRAXXAS TRX4 Trail Crawler and supplied as a 15 pcs set without the cover. Machined from 6061-T6 aluminium, the components are intended to reduce torsional flex and provide a robust mounting platform for rear differential and suspension link interfaces.

The assembly is specified to stabilise rear differential parts, secure the rear axle mount used by suspension links, and reinforce rear C-hub mounting points under crawling loads. Supplied fasteners are matched to the TRX4 rear assembly to ensure correct seating and repeatable alignment during low-speed technical operation.

  • Material: Aluminum 6061-T6
  • Model Number: TRX4013B

Designed with a focus on precision fit and durability, this aluminium rear gear box set replaces plastic mounting points and provides the necessary hardware for a solid, long-lasting rear assembly.

What are the dimensional tolerances for the machined parts?

Components are produced to tight machining tolerances appropriate for direct replacement of TRX4 rear mounts; inspect parts on receipt for any transit damage before installation.

Will these parts change the factory alignment settings?

The aluminium parts aim to maintain factory alignment by eliminating flex at critical points; small checks and adjustments may still be necessary after fitting to ensure correct geometry.

What maintenance is recommended for aluminium mounts?

Regular inspection for fastener security and surface corrosion is advised; use appropriate thread-lock on steel screws and keep mating surfaces clean for best long-term performance.

Is additional machining required for aftermarket link kits?

Aftermarket link or axle conversions may need verification for clearance; these parts are dimensioned for standard TRX4 rear geometry and may require minor adjustments for heavily modified setups.
