TRAXXAS TRX4 Pendulum Wheel Knuckle Weight 6mm Hex Adapter TRX4023 Low-Speed Upgrade by GPM  [TRX4023]

Wheel-end pendulum weight for better traction

The GPM TRX4023 is an aftermarket pendulum weight designed to add mass at each wheel hub of TRAXXAS TRX4 scale crawlers to improve traction and stability when moving slowly over rough ground. The pendulum assembly fits to the knuckle outer case and uses a larger 6mm hex adapter to keep the weight hanging down as the suspension articulates.

Purpose and tuning notes: by concentrating mass lower at the wheel, the kit helps the TRX4 hold contact on climbs, across rutted lines and when pulling out of soft spots. It is sold as a tuning accessory and does not alter suspension geometry or serve as a structural component.

Construction and durability: stainless rolling beads and stainless fasteners pair with an aluminium body to provide additional rotating mass at the wheel end while offering resistance to corrosion during wet or muddy use.

For scale crawler pilots focused on technical lines, the GPM TRX4023 pendulum kit is a compact, corrosion-resistant option to boost wheel bite while remaining easy to fit on standard knuckle outer cases.
