CNC aluminium rear gear box for TRX4

This scaled aluminium rear gear box assembly is produced for the TRAXXAS TRX4 Trail Crawler and sold as a 15 pcs set without the cover. Fabricated from 6061-T6 aluminium, the replacement parts cut down on flex and boost longevity at the differential and suspension attachment points.

The assembly's purpose is to stiffen the rear differential area, secure the rear axle mount used by the suspension links, and reinforce the rear C-hub fixing points when crawling over rocks and roots. Included fixings are supplied to match the TRX4 rear layout so the aluminium pieces sit correctly and retain alignment during technical manoeuvres.

Specifications

  • Item: Aluminum Rear Gear Box (Without Cover) - 15 pcs set
  • Material: Aluminum 6061-T6
  • Model Number: TRX4013B
  • Compatibility: TRAXXAS TRX4 Trail Crawler

If you run demanding trail lines, this aluminium rear gear box set replaces weaker plastic mounts and supplies the correct screws for a clean, reliable installation that keeps the rear geometry true.

Will this work with link-locked or portal axle setups?

The parts are tailored to standard TRX4 Trail Crawler rear mounts; modified axle setups may need additional checking for clearance and fitment.

Does the aluminium set change handling on the trail?

By reducing flex at the mounting points, you should notice more consistent axle alignment and predictable steering response at low speeds.

Are thread-lock or washers required for assembly?

The kit includes the listed screws; use a light thread-lock on steel fasteners if you plan high-torque or repeated disassembly cycles.

Can I reuse stock plastic parts with this kit?

Some plastic pieces may be reused if undamaged, but the aluminium parts are intended to replace the plastic mounting points for improved durability.
