Brass steering weight designed for TRX-4 knuckles

The JR-TRX426 is a brass counterweight intended for installation at the steering knuckle on Traxxas TRX-4 chassis, adding concentrated mass to influence steering inertia on scale trail crawlers.

Compatibility: made for Traxxas TRX-4 platforms as an optional steering block / knuckle counterweight. The part typically uses existing knuckle mount points and compatible hardware from TRX-4 knuckles, so routine hobby tools will usually suffice for fitting.

Tuning notes: the additional brass moves mass outward at the wheel hub, which raises rotational inertia and can reduce steering twitchiness while improving low-speed centering and stability; test changes alongside suspension and tyre choices to dial in handling.

Consider this brass counterweight as a subtle tuning component to refine steering behaviour on TRX-4 crawlers; evaluate its effect incrementally while adjusting complementary setup items.

Brass resists corrosion better than many steels, but keep mating surfaces and threads clean and dry where possible; occasional inspection and light lubrication help prevent galvanic issues with mixed metals.
Compare steering return speed and low-speed tracking before and after installation on the same trail run; small incremental tests reveal the practical benefit without masking other setup variables.
Using a medium-strength threadlocker on knuckle fasteners is a good practice to prevent loosening from vibration, provided you select a product compatible with brass and surrounding hardware.
Tyre choice affects steering feedback and bite; pair the counterweight with tyres that match your desired low-speed traction so the added mass complements rather than conflicts with grip characteristics.
