Knuckle pendulum weight upgrade for TRX4

This kit provides an RC-scale pendulum wheel knuckle axle weight plus a 9mm hex adapter built for the TRAXXAS TRX4. Its role is to add downward mass at each wheel so tyres keep contact during slow crawling and when negotiating obstacles or soft ground.

The pendulum uses stainless steel rolling beads to focus extra mass lower on the wheel assembly, creating consistent downward loading. The result is more weight at the wheel edge to help the tyre bite when the chassis tilts or a wheel plunges into a depression.

Materials include a brass pendulum housing and stainless steel beads and screws. The beads are removable, allowing stepwise adjustment of wheel-end mass. Install on the outer cover of front and rear knuckles so added load is applied without changing steering or suspension geometry.

  • TRAXXAS TRX4 Defender Trail Crawler

Does this kit fit TRX4 axles directly?

Yes, the pendulum housings mount to the outer case of the front and rear wheel knuckles and the 9mm hex adapter is supplied for wheel fitment as noted in Specifications.

How heavy is each unit with beads installed?

Each pendulum assembly weighs about 108g when the stainless beads are fitted, offering a noticeable increase in wheel-end mass for crawling stages.

Can I remove beads for lighter handling?

Yes, beads are removable. Reducing bead count lowers wheel-end mass and can improve steering responsiveness at the cost of some low-speed traction.

Are replacement beads available?

The kit includes removable stainless beads; source replacements or alternatives from stainless hardware suppliers if you need extra or spare beads for further tuning.
