Refine TRF421 Performance Using Tamiya 42386 Axles

Small parts make a noticeable difference. The Tamiya 42386 wheel axles are produced for the TRF421 chassis so you get consistent axle alignment and smoother power delivery.

Fitment and Purpose

These Tamiya TRF421 wheel axles are built to complement the TRF421 chassis kit and are specified for use with Item 42357 Cross Joints to promote a low friction assembly. They suit modelers aiming to improve drivetrain efficiency.

Securing and Shaft Type

Axles are fixed with grub screws for a dependable join. They will not work with clip-type shafts, so double-check your shaft fastening style before purchase or fitment.

Do these axles affect handling?

Indirectly. By lowering drivetrain friction and improving axle alignment, they can contribute to more predictable throttle response and consistent handling lap to lap.

Is Item 42357 mandatory to use these axles?

Item 42357 Cross Joints are the recommended match to achieve the intended low friction setup. Using mismatched joints may increase play or friction.

Best practice for tightening grub screws?

Tighten until secure but avoid over-torquing. Re-check after running and re-tighten if any movement is detected. Use thread locker only if you understand the service implications.

Can I reuse old cross joints with these axles?

You can, provided the old cross joints are in good condition and match the dimensional requirements. Worn joints may negate the low friction benefits.
