Axial EXO Alloy Front Knuckle Arms EX021 Upgrade by GPM  [EX021]

EXO alloy front knuckle arm

This pair of alloy front knuckle arms is offered as a replacement for the factory plastic units on Axial EXO chassis. The listing covers one pair and describes the pieces as alloy components suitable for enthusiasts seeking a metal upgrade.

In use these alloy knuckles function as both a tuning part and a durability improvement: metal knuckles can influence steering feel and extend service life in the front suspension and linkages. Installation is performed at the stock mounting points and typically reuses existing pins, spacers, and fasteners from the EXO assembly.

Note that this is designed for scale RC EXO platforms, not for road vehicles. Always confirm fitment on your EXO variant and inspect thread engagement and clearance after fitting to ensure reliable operation of the steering system.
