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

XO-1 Front Knuckle Arm Details

This aluminium front knuckle arm is supplied as a pair for the TRAXXAS XO-1 platform and is designed for hobby-scale RC use only. It provides a tight, low-tolerance fit intended to reduce play between the steering linkage and knuckle, helping to sharpen steering response without changing the chassis geometry.

Fitment is intended for direct replacement on XO-1 steering assemblies where the standard knuckle dimensions match. Installation is typical for front knuckle swaps: remove the wheel hub components, replace the knuckle arm, verify pinion and hub alignment, then reassemble and check steering throw and toe settings during setup. This part functions as a tuning component to refine steering feel and repeatability when dialling in alignment and suspension tuning on track setups.

Choose this aluminium pair when you need a precise, repeatable knuckle arm for XO-1 setups; verify fit and linkage clearance during installation and use alignment checks when tuning.
