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

Pendulum weight to increase wheel bite on slow crawls

The GPM TRX4023 kit adds focused mass at the wheel hubs of TRAXXAS TRX4 crawlers to aid traction and steadiness at slow speeds. A pendulum weight is coupled with a widened 6mm hex adapter so the mass hangs lower and maintains downward force as suspension travel changes.

Intended use and tuning effect: this accessory lowers local CG at the wheel end, aiding grip during climbs, slot-crossing and recovery from low obstacles. It mounts to the knuckle outer case and is intended as a tuning part rather than a structural chassis component.

Corrosion and construction details: stainless rolling beads and stainless hardware are paired with an aluminium housing to increase rotating mass while offering resistance to corrosion in wet or muddy running conditions.

If you run technical trails and want to boost wheel contact without heavy chassis changes, the GPM TRX4023 pendulum kit adds dependable mass at the wheel ends and is simple to fit to standard knuckle outer cases.
