Upgraded aluminium rear gear box for TRX4

This scaled aluminium rear gear box assembly is intended for the TRAXXAS TRX4 Trail Crawler and is supplied as a 15 pcs set, sold without the cover. Carefully machined from 6061-T6 aluminium, the replacement parts aim to lower flex and improve long-term durability around the rear differential and suspension attachment points.

The assembly helps stabilise rear differential components, secure the rear axle mount for suspension links, and reinforce the rear C-hub fixing points when tackling technical trails. Included screws are provided to match the TRX4 rear assembly so that the aluminium parts locate properly and retain correct alignment during slow-speed crawling.

Specifications

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

For owners wanting firmer rear mounting points, this aluminium rear gear box set replaces weaker plastic fittings and supplies the screws for a direct installation that keeps rear geometry stable in rough terrain.

Is this compatible with the full-size scale TRX4 kits?

This kit is specified for the TRAXXAS TRX4 Trail Crawler rear assembly; confirm your specific kit variant and link geometry against the listed compatibility before purchase.

Will aluminium mounting points crack like plastic can?

Aluminium is less likely to deform under load than plastic; while it can dent under extreme impacts, it generally offers more reliable mounting and repeatable alignment for trail use.

Do I need to shim anything after fitting?

Most installs will not require shimming if the parts are fitted with the supplied screws, but always check link angles and clearances after assembly and adjust as needed.

Can the stock servo and electronics remain unchanged?

The aluminium rear gear box focuses on chassis mounting points and does not necessitate changes to stock servos or electronics unless you are pursuing other performance upgrades.
