HRXMX11HD - Hardened Steel HD Differential Gear Set

This hardened steel heavy‑duty differential gear set is engineered to replace the stock differential gears in Traxxas X‑Maxx and similar large‑scale vehicles. The gears are made from heat‑treated steel with precise tooth profiles to withstand high torque and aggressive bashing without premature wear or stripping. Designed to mesh smoothly under load, the hardened tooth surfaces reduce drivetrain lash and improve power transfer consistency. The set fits directly into the factory differential housing, maintaining correct gear alignment while significantly increasing durability over stock components.
