TRAXXAS TRX4 Pendulum Wheel Weight 23mm Hex Adapter Upgrade TRX4023E by GPM  [TRX4023E]

Pendulum hub weight for TRX4 crawlers

This aluminium pendulum wheel knuckle axle weight uses a 23mm hex adapter to provide low-mounted mass at the wheel hub, intended for the TRAXXAS TRX4 Trail Crawler to enhance stability on rock and technical trails. A bearing runs in a Delrin collar and the pendulum is tapered so the lower mass remains centred downwards while joints articulate at steep angles.

The part effectively raises each wheel's contact force to help maintain traction over uneven obstacles, cut wheel hop in slick patches, and let the crawler hold sharper approach angles without losing grip. Fitment is intended for the outer drive portal or hub area to keep chassis mass low and close to the axle plane.

Included retrofit hardware comprises 23mm hex adapters, stainless steel shafts, spring steel shims, metal washers, and stainless hex socket screws. The supplied bearing assembly and item count are designed for hobby RC use only.

A practical upgrade for TRX4 operators wanting a low-centre solution to improve grip and reduce hop, built around a compact bearing-supported pendulum design.
