TRAXXAS E-MAXX Alloy Front and Rear Knuckle Arm Set EMX2021 by GPM  [EMX2021]

Robust alloy knuckles for E-MAXX tuning

This is an RC-scale alloy front and rear knuckle arm set made for the TRAXXAS E-MAXX platform, model EMX2021. The parts are intended as direct replacement or upgrade components for hobby-grade E-MAXX models to address wear or to alter steering stiffness and response. Materials and shaping prioritise durability for typical off-road and track use in 1/8 or similar electric monster truck applications.

The knuckle arms fulfil two main roles: they locate the steering hub and transfer suspension loads into the upright and suspension geometry, and they affect steering feel when used with different turnbuckle lengths or shock valving. Replacing factory plastic knuckles with alloy units reduces flex and delivers more consistent steering inputs, helping with precise tuning of toe and camber under load.

Installation needs standard disassembly of the front or rear hubs and swapping the factory knuckles with the alloy units using the original hardware. Check ball stud clearances and confirm steering stops and suspension travel remain correct after fitting. Use a light thread locker on mounting screws where metal-to-metal contact is present.

These alloy knuckle arms offer a practical upgrade path for E-MAXX owners seeking firmer steering and longer component life; verify fitment and torque values for your chassis before extended running.
