TRAXXAS TRX4 Aluminum Pendulum Wheel Knuckle Axle Weight with 6mm Hex Adapter by GPM TRX4023  [TRX4023]

Pendulum wheel weight for TRX4

This GPM TRX4023 aftermarket kit adds concentrated mass at each wheel hub for TRAXXAS TRX4 scale crawlers to improve low-speed traction and stability on uneven terrain. The part combines a pendulum-style weight with a widened 6mm hex adapter so the added mass tracks downward and maintains consistent contact force as the suspension articulates.

Design intent and tuning role: the pendulum weight shifts the center of gravity locally toward the ground at each wheel, helping a TRX4 to maintain grip when climbing, crossing ruts, or extracting from soft or low-lying sections. It is a tuning accessory rather than a structural chassis component and is installed on the outer case of the front and rear knuckles where it augments wheel load without changing suspension geometry.

Construction and corrosion resistance: the assembly uses stainless steel rolling beads and stainless fasteners combined with aluminum bodywork, providing a heavier rotating/wheel-end mass while resisting corrosion in muddy or wet running conditions.

For TRX4 owners looking to fine-tune low-speed traction and increase wheel bite in technical crawling, the GPM TRX4023 pendulum weight kit is a targeted accessory that adds mass at the wheel ends while remaining corrosion resistant and simple to fit on standard knuckle outer cases.
