TRAXXAS XO-1 Aluminium Front Knuckle Arm Pair - XO021 by GPM  [XO021]

Knuckle Arm Summary

Supplied as a matched pair for the TRAXXAS XO-1, this aluminium front knuckle arm is aimed at hobbyists tuning for track performance. The low-clearance fit reduces steering linkage slop to give a more precise and predictable response without changing chassis geometry.

Fitment is intended as a direct swap where original knuckle dimensions align. Typical installation involves removing the wheel hub assembly, fitting the new knuckle arm, checking pinion and hub alignment, then reassembling and setting steering throw and toe. Use this component when dialling in alignment and suspension settings for consistent handling.

Opt for this aluminium pair to tighten steering feel on XO-1 rigs; inspect linkage clearance and run alignment checks after fitting.
