Adds low-mounted weight to the wheels to improve traction, stability, and climbing performance on challenging terrain. Constructed from aluminum, it provides a durable and balanced solution for enhancing crawler performance without excessive strain on components. By lowering the center of gravity, it helps reduce rollovers and improves control during steep climbs and side angles. Designed for easy installation, it fits securely within compatible wheel setups for consistent performance. Ideal for upgrading 1/10 scale RC crawlers seeking better balance and grip.
