This CNC-style alloy front one-way is a precision upgrade for the Tamiya TT01 front drivetrain, intended to refine front wheel engagement and release characteristics on-road. The alloy construction improves dimensional stability and wear resistance versus common polymer units, delivering repeatable front response for advanced setup work.
Technical fit note: the unit replaces the TT01 front one-way assembly and requires removal of the existing component; confirm axial play and engagement clearance during installation. In tuned setups, the one-way provides a controlled release profile that influences understeer and oversteer when adjusted together with damper rates, anti-roll bars and tyre compounds.
