Track-Ready TRF421 Upgrade: Tamiya 42385 45mm Shafts

The Tamiya 42385 45mm hard swing shafts are tailored to the TRF421 chassis to cut drivetrain vibration and support cleaner steering inputs. The drive pin and cross shaft are arranged at 90 degrees to limit harmonic movement under load.

Durability and Fitment

Designed to be both light and tough, these shafts give a solid connection that resists bending. They are aimed at drivers who want dependable performance during regular track use and intense sessions.

Installing the Shafts

Fit the shafts in a clean workspace, remove any debris from housings, and confirm free spin after assembly. Tighten fasteners to spec and recheck alignment after a short test run.

Do these replace the stock swing shafts directly?

They are intended as a direct upgrade for the TRF421. Confirm orientation and any washers or spacers during installation to match factory fitment.

Which surfaces benefit most from this upgrade?

High grip and smooth tarmac tracks will show improved steering feedback most clearly, though reduced vibration helps on most surfaces.

What basic tools do I need to fit them?

You will need standard hex drivers, a small screwdriver for clips, and a clean workspace. Calipers help verify correct seating if you have them.
