This replacement body post set is designed for the Tamiya TT-01 Type-E chassis and carries model TT01-M04. The parts provide direct replacement of worn or broken mounting posts and allow controlled changes to mounting height to suit setup needs.
Installation is performed by removing the painted shell, extracting the existing posts, seating the replacement posts into the factory mounting locations and refitting the original fasteners. The fitment preserves factory geometry so chassis alignment and shell orientation remain repeatable across service intervals.
From a setup and tuning perspective these posts stabilise the body at attachment points, reducing flex that can affect aerodynamic testing and clearance measurements. Use them as part of routine maintenance and when rapid body swaps are required during competitive running.
