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

Front knuckle arm for EXO platform

This alloy front knuckle arm serves as a scale replacement for the standard plastic knuckles fitted to Axial EXO chassis. Supplied as a one-pair set, the components are identified as alloy parts suitable for hobbyists wanting a metal upgrade.

Replacing stock plastic knuckles with alloy units is primarily a tuning and durability decision: metal knuckles can alter steering feedback and improve wear resistance in the front suspension and steering linkages. Installation uses the original mounting locations; retain your existing pins, spacers, and fasteners unless they show wear.

Remember this product is intended for RC EXO models only. Verify fitment for your particular EXO variant before fitting, and check thread engagement and clearance after installation to ensure correct suspension and steering operation.
