TRAXXAS TRX4 Front Knuckle Arms 14pcs 6061 T6 TRX4021B by GPM  [TRX4021B]

CNC 6061 T6 knuckles for confident technical crawling

This 14pcs set of aluminium front knuckle arms is made for TRAXXAS TRX4 Trail Crawler scale setups and is built to support and stabilise steering linkages and the internal front knuckle gears to keep gear runs consistent under load.

Parts are machined from aluminium 6061 T6 with a 3D CNC finish to retain rigid geometry while offering a solid metallic feel. The kit works as an aftermarket replacement to reduce play at knuckle pivot points and to help preserve smooth gear engagement during low-speed technical crawling.

Fasteners shown by the product source are stainless steel screws in several sizes for assembly; confirm the included counts before fitting and use proper thread engagement and locking methods for your chassis.

Fit these knuckle arms when you want firmer steering geometry and less slop at the front knuckles; they act as a tuning part to stabilise gear engagement and improve predictability on slow technical lines.
