TRAXXAS TRX4 Wheel Knuckle Pendulum Weight with 23mm Hex Adapter TRX4023XX by GPM  [TRX4023XX]

Brass pendulum wheel weights for TRX4 hubs

This pendulum wheel weight set is intended for TRAXXAS TRX4 trail crawlers to increase mass at the wheel and lower the effective centre of gravity for improved traction at low speeds. The brass pendulum tapers at the top and flares at the bottom, running on a bearing with a Delrin collar to keep the mass hanging downward across a broad range of wheel angles. That behaviour helps tyres regain contact on uneven or recessed surfaces and allows larger crawl angles.

The assembly fits at the outer drive portal and needs wheels with a 45mm inner bore and a 5mm thread hole. The supplied 23mm hex adapter moves the hex outboard relative to stock to accommodate the pendulum. Each pendulum plus hex assembly weighs 133 grams and the 12-piece set is sold as an aftermarket upgrade for crawler wheel hubs only.

Fit these brass pendulums to add wheel-end inertia for more stable technical crawling and improved tyre contact; always check wheel bore and thread compatibility first.
