Sharper steering for TRF421 race setups

The Tamiya 9803493 Knuckle Arm Set upgrades the TRF421 front assembly with a blue finish and reinforced pivot points. These knuckles aim to reduce steering play and deliver a more consistent turn-in, suiting circuit racers looking for predictable handling.

Specifications

Color: Blue colour
Compatibility: Compatible with TRF421 chassis
Pieces: Two pieces

A sensible upgrade for racers seeking cleaner steering behaviour and extended part life on track.

Will these knuckles change steering feel drastically?

They refine steering by reducing flex and play at the front end. Expect firmer feedback rather than a wholesale change in steering geometry.

Do I need different bearings or hardware?

Standard TRF421 bearings and hardware continue to work. Swap any worn ballcups and ensure fasteners are torqued to spec to maintain alignment.

How often should I inspect these parts?

Check knuckles after every few race sessions for play and finish wear. Regular inspection helps catch early wear before it affects handling.
