TRAXXAS TRX4 Pendulum Wheel Knuckle Weight with 23mm Hex Adapter TRX4023E by GPM  [TRX4023E]

Low-mounted pendulum weight for TRX4

This aluminum pendulum wheel knuckle axle weight fitted with a 23mm hex adapter is a retrofit accessory for the TRAXXAS TRX4 Trail Crawler that adds mass low at the wheel hub to aid stability while crawling. The assembly centres on a bearing with a Delrin collar and a tapered pendulum profile that is slim at the top and broader at the base so the mass stays gravity-biased while allowing wide articulation angles.

In use the component increases the effective weight at each wheel to help maintain tyre contact on rough lines, reduce wheel hop in low-traction sections, and enable the crawler to hold steeper approach angles without losing grip. It is designed to mount at the outer portal or wheel hub area to keep the car's center of mass lower relative to the axle.

The supplied hardware supports retrofit installation and includes 23mm hex adapters, stainless steel screw shafts, spring steel shims, metal washers, and stainless steel hex socket screws. The kit quantity and the bearing-equipped assembly are sized for hobby-grade RC applications only.

This kit is aimed at TRX4 owners looking for a simple way to lower effective wheel mass and improve traction through technical obstacles, using a compact bearing-mounted pendulum that keeps weight biased downward during articulation.
