TRX4 Pendulum Wheel Weight Kit with 23mm Hex Adapter TRX4023D TRX4023 by GPM  [TRX4023D]

Low-mounted pendulum weight for TRX4 knuckles

This pendulum wheel weight is made for the TRAXXAS TRX4 Trail Crawler and pairs an aluminium outer body with removable stainless steel rolling beads to shift rotating mass lower on each wheel. The assembly adds controlled weight low and slightly outward on the knuckle outer case to boost wheel bite on low obstacles and soft surfaces while maintaining pendulum action.

The kit includes a wider 23mm hex adapter, a multi-piece bead stack for progressive weight tuning, and the mounting hardware required for fitment. Each wheel unit accepts up to eight removable stainless steel beads at about 4g per bead, yielding a per-piece mass in the region of 44-64 grams when fully populated.

When installed on the front and rear outer cases of the wheel knuckles the pendulum weight preserves free movement so the added mass naturally settles to the lowest point during suspension travel. Change bead count to tune low-speed traction versus responsiveness; the maker suggests retaining at least three beads for consistent behaviour.

Use this kit to dial in wheel bite and slow-speed crawling stability on the TRX4 by adding downward-oriented mass at each wheel with easy incremental bead adjustment.
