Trail Pendulum Wheel Weight Set TRX4023DX for TRAXXAS TRX4 by GPM  [TRX4023DX]

Pendulum axle weights for better grip on trails

A 12-piece pendulum-style wheel weight kit made for TRAXXAS TRX4 scale crawlers. The unit combines a brass body with an alloy lid and removable stainless steel rolling beads so each wheel can carry extra downforce without changing the suspension geometry. The pendulum keeps mass low and close to the tyre contact patch to maintain wheel traction during slow crawling and when exiting low spots.

Mounting is on the outer knuckle case at both axles, so internal axle components remain untouched. You can fine tune weight by adding or removing up to eight stainless beads per unit, each about 4g, providing a per-wheel mass window around 66g to 86g depending on configuration. The package includes a 23mm hex adapter for wider wheel hubs.

Parts are selected to cope with muddy or wet trails, with stainless beads and hardware to reduce corrosion risk versus untreated metals. The pendulum action provides a steady downward bias through wheel rotation so the change targets traction behavior rather than steering geometry.

Ideal for hobbyists tuning low-speed bite and balance, this pendulum kit gives a corrosion-resistant, adjustable option to help TRX4 wheels track and recover more consistently on technical trails.
