The Tamiya 54311 RC TA06 Cross Shaft for Gear Differential Unit OP-1311 is a straightforward upgrade for builders who want a firmer drivetrain. Replacing the factory resin cross shafts with metal units increases stiffness and helps the differential run more smoothly under load.
Metal cross shafts reduce flex compared to resin originals, keeping gears better aligned during hard acceleration and corner exits. That stability can deliver more predictable handling and reduced wear on gear teeth when driving hard or racing on abrasive surfaces.
These metal cross shafts are designed for the TA06 platform and fit the TA06 PRO as well. Installation is basic: remove the old resin shafts from the gear differential unit and press in the metal replacements. No special machining is required for a standard TA06 setup.
