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

Precision Knuckle Arm Overview

This aluminium front knuckle arm is supplied as a pair for the TRAXXAS XO-1 platform and is built for hobby RC track use. It features a low-tolerance fit to minimise play at the steering linkage, sharpening steering response without changing the vehicle geometry.

Designed for direct replacement where standard knuckle dimensions match, installation follows the usual front knuckle swap routine: remove wheel hub parts, fit the new knuckle arm, confirm pinion and hub alignment, then reassemble and check steering throw and toe during setup. Use this part as a tuning item to improve steering feel and repeatability when refining alignment and suspension for circuit running.

Select this aluminium pair when you want a precise, repeatable knuckle arm for XO-1 track setups; always verify linkage clearance and perform alignment checks after fitting.
