Tamiya 9804251 One-way Joint Cup for TG-10 Mk.II - Race Day Tweak  [9804251]

Enhance TG-10 Mk.II Drive with the 9804251 Joint Cup

Owners of the Tamiya TG-10 Mk.II will find the 9804251 One-way Joint Cup a handy handling upgrade. It allows the differential to act in one direction only, which can streamline power transfer and reduce backlash under certain conditions. These traits help when you need more predictable responses through bends.

Why It Helps Your Setup

The Tamiya 9804251 One-way Joint Cup is aimed at drivers who want tighter control over corner behaviour. By limiting differential action to a single direction, it can make turn-in crisper and exits more controlled, useful for timed runs and practice sessions. It installs cleanly into compatible drivetrains without major changes.

Simple Fitment Notes

Fitting is straightforward for anyone comfortable with basic drivetrain work. Prepare a clear bench, remove the relevant driveline parts from your TG-10 Mk.II, then install the joint cup following normal reassembly steps. Once fitted, expect improved stability during quick direction changes and accelerations.
