Precision pendulum hub weight for TRX4 applications

This CNC-friendly aluminium pendulum wheel knuckle axle weight with an integrated 23mm hex adapter is a precision upgrade for the TRAXXAS TRX4 Trail Crawler that concentrates mass low and outboard at the wheel hub to improve static and dynamic traction. The design features a centrally located bearing running in a Delrin collar and a tapered pendulum profile that narrows toward the top and flares at the base to preserve a gravity-biased centre of mass while permitting full articulation.

From an engineering standpoint the assembly increases effective wheel load to maintain tyre contact over irregular terrain, mitigates wheel hop under low traction, and supports steeper approach and climb angles without sacrificing grip. The component is intended for installation on the outer drive portal or hub flange to keep unsprung mass oriented low relative to the axle assembly.

The kit includes retrofit hardware optimised for hobby use: 23mm hex adapters, stainless steel screw shafts, spring steel shims, precision metal washers, and stainless hex socket screws. The supplied bearing and component count are specified for RC hobby duties and routine maintenance intervals are recommended for long-term reliability.

  • TRAXXAS TRX4 Defender Trail Crawler

What bearing specification is used in the assembly?

The kit uses a hobby-grade radial bearing sized to seat within the Delrin collar; confirm bearing dimensions with the included hardware when replacing or sourcing spares.

Are the hex adapters machine tolerant for hub runout?

The 23mm hex adapters are designed to provide a snug fit while allowing slight tolerance for minor hub runout; ensure adapters are installed flush and fasteners torqued to avoid side load on the bearing.

Recommended inspection intervals?

Inspect the bearing, Delrin collar, shims and fasteners after the first few runs and then periodically depending on use; replace worn components to maintain optimal performance.

Can the kit be used with modified gear ratios or heavier tyres?

The pendulum increases wheel-end mass and will interact with drivetrain loads; when using heavier tyres or altered gearing, verify bearing load and driveline stresses to ensure component longevity.
