Aftermarket brass counterweight for TRX-4 knuckles

The JR-TRX426 is an aftermarket brass counterweight intended for Traxxas TRX-4 steering knuckles, adding localised mass at the hub to change steering inertia on scale trail crawlers.

Compatibility: built for Traxxas TRX-4 scale and trail crawler platforms as an optional steering block / knuckle counterweight. Fitment normally uses existing knuckle mounting points and common TRX-4 hardware, so ordinary hobby tools are usually adequate for installation.

Tuning summary: fitting brass at the knuckle increases rotational inertia, which can slow steering return and improve low-speed stability and centering; evaluate its effect alongside suspension damping and tyre setup to reach the handling you want.

This brass counterweight is a focused tuning accessory for drivers adjusting front-end steering feel on TRX-4 models; introduce it incrementally and pair with complementary setup tweaks.

No special machining is normally required; the counterweight is made to mount to standard TRX-4 knuckle attachment points, though confirm compatibility with any non-stock knuckles prior to fitting.
The change is subtle but tangible: expect a slower steering return and firmer self-centering at low speeds; combine with suspension and tyre tuning to refine the net effect.
Brass is durable for scale use, but monitor contact interfaces and fasteners during routine checks to ensure no wear or loosening develops over time.
This is an aftermarket accessory; check your vehicle manufacturer warranty terms—fitting third-party components can affect coverage in some cases.
