Precision CNC knuckles for TXT platforms

This TXT021 knuckle arm set is a CNC-oriented 6061-T6 aluminum steering upgrade for TAMIYA TXT and Juggernaut II 4X4X4 chassis. Designed with focus on pivot stiffness and repeatable geometry, the machined parts reduce deflection compared with the original plastic knuckles and maintain alignment under load. The kit includes the small, specialised hardware required to mount the knuckles as a direct replacement without major chassis changes.

Intended for performance-minded hobbyists and workshop tuning, the components integrate with stock kingpin and delrin collar arrangements; perform a dry fit to confirm tolerances and clearances before final assembly and thread-lock application. Regular inspection of pivot wear and fastener torque is recommended to retain precise steering characteristics.

Packing includes

  • Knuckle arm - 2pcs
  • Special king pin - 4pcs
  • Special delrin collar - 4pcs

Compatible Models

  • TAMIYA-TXT
  • TAMIYA-JUGGERNAUT II 4X4X4 SERIES

A precision aluminium knuckle solution for TXT and Juggernaut II chassis, suited to tuners seeking improved steering feedback and component longevity; validate fitment carefully during installation.

What machining finish is used on these knuckles?

The knuckles are machined from 6061-T6 billet with attention to pivot bore tolerances to ensure consistent kingpin seating and reduced runout compared with molded parts.

Are any modifications needed to fit TXT021 parts?

TXT021 is made to be a direct-fit replacement for standard TXT kingpin and collar setups. A dry assembly is advised to confirm fit; no permanent modifications should be necessary for correctly spec chassis.

Which inspections are recommended after install?

After initial installation, verify kingpin alignment, torque values, and collar seating. Recheck after the first running session to detect any seating or wear issues early.
