Refine Your TRF421 with the Tamiya 3451519 Centre Shaft

The Tamiya 3451519 centre shaft is a high-precision component for pilots committed to sharper drivetrain performance on their TRF421. It focuses on trimming slop so power transfer feels more direct under acceleration.

Precision That Improves Handling

Specifically matched to the TRF421 geometry, this centre shaft is made to withstand regular track use while tightening driveline feedback. Expect improved mid-corner stability and cleaner exits when accelerating.

Ease of Setup for Competitive Runs

Quick to fit into a TRF421, the Tamiya 3451519 allows you to get back to setup work and tyre/ride-height changes without fuss, helping you optimise lap consistency.

It is intended for the TRF421 form factor. Some older TRF models differ in spacing and may require adapters or machining to fit correctly.
By reducing unwanted movement in the driveline, the shaft can help even out gear loading and may lower uneven wear when installed and maintained properly.
After fitting, recheck pinion and spur engagement and run a few low-speed laps to confirm there is no binding. Fine tune drivetrain alignment if needed.
