The Traxxas 7756X aluminum wheel hex hubs are precision‑machined replacement components that provide increased strength and durability over standard plastic hex hubs, helping to reduce wear and flex under high‑stress driving conditions while maintaining a reliable connection between the wheels and axle, and designed to resist damage from impacts and hard landings for longer‑lasting performance. These aluminum hex hubs are compatible with a variety of Traxxas 1/10‑scale vehicles that use aluminum wheel hex upgrades, including Traxxas Slash, Traxxas Rustler, Traxxas Stampede, and similar models that accept 12 mm wheel hex hubs.
