Knuckle-mounted brass mass for wheel inertia tuning

The JR-TRX426 brass counterweight is an aftermarket knuckle accessory created to add measurable mass at the wheel hub of Traxxas TRX-4 vehicles, letting drivers tune steering response on scale crawls and trails.

Compatibility: intended for Traxxas TRX-4 scale and trail crawler models as an optional steering block / knuckle counterweight. Installation generally uses the factory knuckle mounting points and regular hardware common to TRX-4 knuckles; standard hobby tools are normally adequate.

Tuning impact: by increasing rotational inertia at the wheel, the counterweight can slow steering return and stabilise the front end at low speeds, which is useful when negotiating rough sections; make changes in steps and observe how suspension damping and tyre selection interact with the added mass.

Use this brass counterweight as a targeted tuning tool to change steering behavior on TRX-4 rigs; pair it with progressive setup testing instead of sweeping adjustments.

What tuning goals suit this part?

This counterweight is best when you want slower steering return and stronger self-centering at low speeds; it helps on technical sections where precise steering hold is more valuable than rapid snap-back.

Will it make understeer worse?

The added front mass can shift balance toward understeer in some setups; if that occurs, consider softening front rebound or adjusting tyre choice to recover desired turn-in characteristics.

How should I test its effect?

Run back-to-back trials on the same section with and without the weight, noting steering return, cornering entry, and low-speed tracking; record changes to damping and tyre pressures that improve the result.

Does suspension need revalving?

You may need minor damping adjustments rather than full revalving; increasing rebound or fine-tuning compression can help the chassis react predictably to the altered front-end inertia.
