Axial EXO Alloy Front Knuckle Arm EX021 by GPM  [EX021]

Alloy front knuckle for EXO chassis

This alloy front knuckle arm is a scale replacement designed for the Axial EXO platform. It replaces the factory plastic knuckle on EXO-series chassis when a metal upgrade is preferred. The part is supplied as a single pair set and is listed as an alloy component in the product title.

On the trail or at the track the alloy knuckle serves as a tuning item and a longevity upgrade: swapping plastic knuckles for metal units can alter steering feel and reduce wear on front suspension and steering linkages of the EXO chassis. Fitting requires removing the stock knuckle arm and installing the alloy piece at the original mount points, keeping your existing pins, spacers, and fasteners.

Note that this is an RC-scale accessory intended for EXO models, not full-size vehicles. Confirm fitment for your specific EXO variant before installing, and check thread engagement and clearance after fitting to ensure safe steering geometry and suspension movement.
