Pendulum wheel weights for TRX4

This upgrade kit is an RC-scale pendulum wheel knuckle axle weight and 9mm hex adapter designed for the TRAXXAS TRX4 platform. Its purpose is to add downward mass at each wheel to improve tire contact and crawling stability when negotiating low-speed obstacles and muddy terrain.

The pendulum assembly uses stainless steel rolling beads to concentrate added mass lower on the wheel assembly, producing a consistent downward force. The complete set increases weight at the outer wheel area, helping the tyre maintain traction when the chassis is tilted or when a wheel is digging into a depression.

Materials and hardware provided include brass for the pendulum housing and stainless steel for the rolling beads and fasteners. The beads are removable to allow incremental tuning of wheel weight. Installation is intended for the outer case of the front and rear knuckles, where the part provides additional downward load on the wheel without modifying core steering or suspension geometry.

What is included in the 16 pcs set?

The set includes pendulum weights and associated hardware: 9mm hex adapters (2 pcs), cap head screws, M4 screw shafts, 5mm shims and washers, 10mm hex socket screws and removable stainless steel beads as listed in the specifications.

How do I adjust the weight on each wheel?

Remove or reinstall the stainless steel beads inside the pendulum; each bead is approximately 4g. Up to five beads are provided for incremental adjustments to achieve the desired downward force.

Will the stainless steel beads resist rust on muddy tracks?

The rolling beads and supplied fasteners are stainless steel, which helps resist corrosion in wet or muddy conditions, reducing the risk of rust under normal RC use.

Where are these installed on the TRX4?

Install the pendulum weights onto the outer case of the front and rear wheel knuckles; the design applies added mass outward at the wheel to improve ground contact during crawling.
