Quick Summary

This kit supplies brass inner cases for the rear knuckle arms used on TRAXXAS TRX4 Trail Crawler chassis. Replacing the factory plastic inner housings, the brass units increase rotating mass at the rear wheels and help stabilise the internal gear train for smoother gear engagement when crawling.

The set is supplied with the required stainless steel cap head screws for a direct swap, and the heavier brass pieces are intended to give better wheel bite and maintain consistent knuckle gear behaviour under load.

Consider this as an aftermarket tuning component to fine-tune rear-end feel on technical trails where extra hub mass supports traction and steadier gear meshing. It is not intended to alter steering geometry.

Packing includes

  • Brass Rear Knuckle Arms Inner Case - 2pcs

A practical aftermarket upgrade for TRX4 Trail Crawler enthusiasts wanting added rear hub weight and improved knuckle gear stability; always verify fitment to your vehicle before installing.

Which components are supplied

Two brass rear knuckle inner cases and the stainless steel cap head screws listed in the Packing includes section are included for installation.

Will this affect my steering

No. The part increases mass at the hubs and stabilises internal gears but does not change steering geometry or steering link positions.

Is this suitable for trail recovery situations

Added hub mass can aid recovery by improving wheel bite and helping the knuckle gears maintain engagement during tough, low-traction manoeuvres.

Do I need extra tools to fit it

Installation requires basic hand tools for removing the original screws and fitting the supplied stainless steel cap head screws; no special tools are necessary.
