The Tamiya 49426 Differential Joint upgrades the TRF415 with a lightweight aluminum option finished in blue anodize. It is aimed at drivers who want a clean look plus durable construction in critical drivetrain areas for regular track use.
Aluminum parts like this balance strength and reduced mass, helping maintain drivetrain efficiency while resisting wear. The anodized coating protects against corrosion and keeps the surface resilient under normal racing conditions.
