The Tamiya 53804 TRF415 Reinforced Differential Joint is a straightforward upgrade for drivers wanting a tougher differential component. Molded with 30% glass-reinforced material, it offers improved strength over standard polyester parts while keeping original mounting alignment.
The glass fiber content increases resistance to wear and fatigue, helping the joint stand up to hard launches and repeated track sessions. That added durability reduces the chance of breakage under load.
Designed to fit the TRF415 and TRF415 MS chassis, this joint installs using common hobby tools and factory attachment points so you can swap it in quickly to reinforce the drivetrain.
