TRAXXAS TRX4 Pendulum Weight Upgrade 6mm Hex Adapter Kit TRX4023A by GPM  [TRX4023A]

Dynamic pendulum weights for technical crawling

This 24 piece accessory set is designed for TRAXXAS TRX4 trail crawlers to add rotating mass at each wheel and improve low-speed steadiness. It combines pendulum stainless steel rolling beads with aluminium outer cases and larger 6mm hex adapters so the mass moves lower as wheels turn, helping tyres retain grip on rocks, mud and shallow ruts.

The pendulum layout allows the inner mass to swing and remain oriented downward, producing a steady bias toward the ground instead of simple fixed ballast. That dynamic helps wheels that are digging in or attempting to climb from hollows by increasing the downward force at the contact patch during rotation.

Fitting is aimed at the front and rear outer case areas of compatible knuckles and the kit includes stainless fasteners and widened hex adapters; this is an aftermarket GPM solution compatible with TRX4 style knuckles and not an original equipment item.

For crawler pilots seeking a mechanical method to bias weight toward the tyres, this GPM pendulum kit fits at knuckle outer cases to assist low-speed traction and vehicle balance on uneven ground.
