Specifications

Compatibility: Fits TRF421 chassis
Pieces: 2 pieces

A practical upgrade for drivers wanting firmer steering feel and longer-lasting front-end parts on their TRF421 race cars.

Will the 9803493 fit without trimming or adapters?

These knuckle arms are produced for the TRF421 geometry and normally install without modification. Check suspension ballstud locations and steering link lengths during fit-up to confirm alignment.

What maintenance keeps these knuckles performing well?

Inspect pivot holes for wear, clean away grit after running, and ensure ballcups and pins are correctly greased to prevent premature play.

Are there recommended servo or steering upgrades to pair with these?

For tighter response pair the knuckles with a high-torque, low-play servo and beefy turnbuckles. That reduces slop and lets the 9803493 show its steering benefits.
