TRAXXAS TRX4 Trail Crawler Pendulum Wheel Weight 23mm Hex TRX4023XX by GPM  [TRX4023XX]

Pendulum brass weights for TRX4 hubs

This pendulum wheel weight set is built to suit TRAXXAS TRX4 trail crawlers, adding weight at the wheel to lower the effective centre of gravity and improve slow-speed traction. The brass pendulum is shaped narrow at the top and wide at the base, running on a bearing with a Delrin collar to ensure the mass hangs down through steering and suspension travel. The setup helps tyres re-engage on irregular or recessed terrain and supports larger crawl angles without losing contact.

Installation is intended at the outer drive portal; compatible wheels require a 45mm inner diameter and a 5mm wheel thread hole. The included 23mm hex adapter provides the extra offset versus a stock hex to clear the pendulum. Each pendulum-plus-hex unit weighs 133 grams and the complete offering is an aftermarket wheel hub upgrade for crawlers.

Choose these brass pendulums to add wheel-end inertia for more stable low-speed crawling and better grip on steep or rough terrain; verify wheel bore and thread compatibility before fitting.
