Hobbyists upgrading a TA05 chassis can fit the Tamiya 53919 - TA05 Aluminum Differential Joint to replace the original plastic joint with a robust metal option that reduces friction and extends service intervals.
The Tamiya 53919 is produced from aluminium to offer superior resistance to wear compared to stock plastic joints. The harder material helps limit abrasion and keeps the drivetrain turning smoothly under load.
The kit contains both sizes of TA05 aluminium differential joints, a 5x0.5mm spacer and a swing shaft protector so you can complete the upgrade without sourcing extra parts.
Configured for the TA05 platform, the joint aligns with the chassis geometry and mounting points to preserve handling while improving reliability.
