Tame Your TRF421 Drivetrain with the Tamiya 3451527 Nut

The Tamiya 3451527 nut is designed to lock the spur gear on a TRF421 chassis so gear movement is minimised under braking and acceleration. Its precise fit helps preserve gear teeth and keeps the mesh steady through multiple heats. Install it when overhauling the gearbox or fitting new components to keep the drivetrain tight.

Inspect the nut when you check gear mesh or after any hard impacts; routine checks every few meetings will catch loosening early.
Use the correct sized nut driver or socket and a firm but controlled torque to seat the nut without risking stripped threads.
Yes, it is compact and simple to fit, making it a practical spare for trackside fixes when a loose spur nut causes issues.
