TRX4 Pendulum Wheel Weights with 6mm Hex Adapters TRX4023A by GPM  [TRX4023A]

Pendulum weight upgrade for TRX4 trail rigs

This 24 piece set is a scale accessory made for TRAXXAS TRX4 trail crawlers to add rotating mass at each wheel and boost low-speed traction and overall stability. The kit pairs pendulum-style stainless steel rolling beads with aluminium outer cases and widened 6mm hex adapters to shift mass downward as the wheel rotates, helping the tyre keep contact on uneven, muddy or low surfaces.

The pendulum arrangement lets the inner mass move slightly and remain biased downward, creating a dynamic center of gravity instead of fixed ballast. This behaviour helps when a wheel is digging into soft ground or working to climb from depressions by increasing effective downward force at the tyre contact patch during rotation.

Installation focuses on the front and rear outer case areas of compatible wheel knuckles and uses the supplied stainless fasteners and widened hex adapters; the product is supplied as an aftermarket GPM solution compatible with TRX4 style knuckles rather than an OEM part.

For trail crawlers running low-speed technical lines, this GPM pendulum set offers stainless and aluminium rotating mass that fits the knuckle outer cases to help wheels stay planted and improve traction in muddy or uneven terrain.
