This alloy lower gearbox housing is supplied as the serviceable bottom half for the front drivetrain on the Tamiya TA01 chassis. The machined or cast alloy offers improved stiffness over the original plastic cover and provides a stable mounting surface for the spur and pinion interface.
Removing the lower case grants access to internal bearings, gear engagement and shaft seating for precise inspection and light setup work. The alloy lower shell helps preserve alignment under routine operation and is intended for workshop maintenance and small performance adjustments.
Use this alloy lower shell when you require a robust, service-focused replacement for TA01 front drivetrain maintenance that supports consistent alignment during use.
