The Kyosho TFW121 Steel S-Shaft is a straightforward durability upgrade for TF series cars. Constructed from steel, the 42.5mm pin-type D-joint shaft is built to give a firmer, more consistent connection under normal racing and hobby use.
Designed with a secure pin-type D-joint, the Kyosho TFW121 helps maintain a positive connection between drivetrain components. The accurate 42.5mm length and steel material work together to reduce play and support dependable handling.
This shaft is compatible with a number of TF series variants and fits into typical drivetrains as an OEM-style replacement. It is suitable for replacing worn parts or upgrading where extra strength is needed without reworking the setup.
