TRAXXAS TRX4 Trail Crawler Brass Pendulum Wheel Knuckle Axle Weights by GPM TRX4023XL  [TRX4023XL]

Pendulum wheel knuckle axle weights overview

This is an RC-scale pendulum wheel knuckle axle weight kit designed for TRAXXAS TRX4 Trail Crawler platforms. The assembly uses brass bodies combined with stainless steel rolling beads to add mass low and close to each wheel, helping the tyre maintain downward force during slow, technical crawling and when traversing low-lying terrain.

The kit is intended to be fitted to the wheel knuckle and portal outer drives where applicable, increasing static and dynamic weight at the wheel. The stainless steel rolling beads are removable to allow fine tuning of the total pendulum mass per wheel, and the hardware list in the source provides the fasteners and hex wideners needed for installation on compatible hubs.

Installation notes: align the pendulum assembly to the knuckle or portal flange as required by your TRX4 wheel and hex setup, use the supplied hex wideners to match your wheel hex size, and secure with the provided stainless steel screws and shaft components. Check for free rotation and that added mass does not contact suspension or bodywork at full articulation.

This kit is a hardware-level tuning option for TRX4 crawlers where additional wheel-end mass is desired to improve low-speed traction and stability on technical or soft terrain; use the removable beads and supplied wideners to match wheel setup and tuning goals.
