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

Front Knuckle Arm Brief

Sold as a pair for the TRAXXAS XO-1, this aluminium front knuckle arm is aimed at hobby drivers looking to improve on-track steering precision. The tight machining tolerances reduce play between the knuckle and steering linkage to produce crisper feedback without modifying chassis geometry.

The part is intended as a direct replacement where original knuckle dimensions are the same. Installation is the standard process: remove hub components, fit the knuckle arm, verify pinion and hub alignment, then reassemble and set steering throw and toe as part of setup. This is a tuning component for refining steering feel and repeatable handling while adjusting alignment and suspension for track conditions.

Use this aluminium pair when you need a repeatable, precise knuckle arm for XO-1 tuning; check clearances and perform alignment verification after fitting.
