TAMIYA TXT / Juggernaut II 4X4X4 Heavy-Duty Knuckle Arms 6061-T6 TXT021 by GPM  [TXT021]

Upgrade knuckles for TXT and Juggernaut II

This aluminum knuckle arm kit is a direct-fit steering upgrade for TAMIYA TXT and Juggernaut II 4X4X4 vehicles. Crafted from 6061-T6 aluminum, the replacement knuckles limit flex seen with the stock plastic components and keep steering geometry more consistent during hard use. The kit centres on the steering pivot and includes the small hardware required to complete the swap.

Ideal for tougher off-road runs or competitive weekend events where steering repeatability matters, the parts bolt in place using your existing kingpins and collars. Always verify fit and alignment before final tightening and thread-lock application.

A straightforward metal knuckle replacement for TXT owners aiming for firmer steering and improved longevity; confirm the fit on your chassis before finishing the install.
