TRX4 Crawl Weight Assembly 23mm Hex Adapter TRX4023D TRX4023 by GPM  [TRX4023D]

Pendulum weight upgrade for TRX4 knuckles

Designed for use with the TRAXXAS TRX4 Trail Crawler, this pendulum wheel weight combines an aluminium housing with removable stainless beads to drop the effective centre of mass at each wheel. The layout concentrates weight low and slightly outboard on the knuckle outer case to improve grip on ground-hugging lines and soft terrain while keeping pendulum movement intact.

The package contains 23mm hex adapters that are larger than standard, a segmented bead system for fine tuning, and the fitting hardware required. Each assembly takes up to eight stainless beads at about 4g apiece, producing an installed per-piece mass around 44-64 grams depending on bead count.

Fitted to the front and rear outer cases of the wheel knuckles, the pendulum weights allow the added mass to find the lowest point through suspension travel. Adjust bead quantity to balance wheel bite and steering response; a minimum of three beads is recommended for reliable behaviour.

The kit provides incremental mass tuning for improved low-speed stability and bite during technical crawling on the TRX4 platform.
