TRX4 pendulum wheel-weight upgrade

This kit supplies an RC-scale pendulum wheel knuckle axle weight and a 9mm hex adapter intended for the TRAXXAS TRX4 chassis. It is designed to add downward mass at each wheel to improve tyre contact and crawling stability when negotiating slow-speed obstacles or muddy sections.

The pendulum assemblies use stainless steel rolling beads so the added mass sits lower on the wheel assembly, producing a steady downward force. Overall weight at the wheel rim increases, helping the tyre retain traction when the chassis is angled or a wheel drops into a hole.

The parts are made from brass for the pendulum housing with stainless steel beads and fasteners. Beads are removable to permit incremental tuning of wheel-end weight. Installation is on the outer case of front and rear knuckles so the extra load is applied without changing core steering or suspension geometry.

Specifications

  • Item Pendulum wheel knuckle axle weight with 9mm hex adapter, 16 pcs set
  • Material Brass pendulum housing, stainless steel rolling beads and screws
  • Model Number TRX4023X
  • Compatibility TRAXXAS TRX4 TRAIL CRAWLER

What is supplied in the 16 piece set?

The package contains pendulum weights and the listed adapters and fasteners: two 9mm hex adapters, stainless screws, M4 shafts, shims and washers, 10mm hex socket screws and the removable stainless beads as per Specifications.

How much does each unit weigh?

Each assembled pendulum unit weighs approximately 108g with the rolling beads installed, which significantly affects wheel-end inertia for crawling situations.

Can the weight be reduced for quicker steering?

Yes, removing one or more beads reduces wheel-end mass and will make steering feel more responsive though with slightly less low-speed traction.

Does the 9mm adapter change wheel fitment?

The 9mm hex adapter is 4mm wider than the standard TRX4 hex and is included to match wider wheel setups; check clearance before fitting to avoid rubbing on suspension components.
