TRAXXAS TRX4 Brass Pendulum Wheel Weight Kit 23mm Hex TRX4023XX by GPM  [TRX4023XX]

Pendulum brass wheel weights for TRX4 crawlers

This brass pendulum wheel weight set is designed for TRAXXAS TRX4 trail machines to increase mass at each wheel and lower the vehicle's effective centre of gravity for improved low-speed traction. The pendulum profile is tapered at the top and wider at the base and runs on a bearing with a Delrin collar so the mass hangs downward throughout large suspension and steering angles. The arrangement lets the tyre regain ground contact when negotiating uneven or recessed terrain.

Intended installation is at the outer drive portal area; wheels must have a 45mm inner diameter and a 5mm threaded hole to accept the assembly. The provided 23mm hex adapter moves the hex outboard relative to stock to clear the pendulum. One pendulum plus hex weighs 133 grams and the product is offered as an aftermarket upgrade for crawler hubs only.

Fit these pendulums to add wheel-end inertia for steadier slow-speed crawling and better tyre contact on rough lines; always verify wheel bore and thread fit before fitting.
