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

Alloy Front/Rear Knuckle Arm for E-MAXX

This is an RC-scale alloy front and rear knuckle arm set made for the TRAXXAS E-MAXX platform and supplied by GPM as 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 shape focus on durability under typical off-road and track use for 1/8 or similar electric monster truck applications.

The knuckle arms serve two practical roles: they locate the steering hub and transmit suspension loads into the upright and suspension geometry, and they influence steering feel when paired with different turnbuckle lengths or shock valving. When replacing factory plastic parts with alloy units, expect reduced flex and more consistent steering inputs, which can aid precise tuning of toe and camber under load.

Installation requires standard disassembly of the front or rear hubs and swapping the factory knuckles with the alloy units using the original hardware. Check for proper fit at ball stud connections and verify that steering stops and suspension travel remain correct after installation. Light thread locker on mounting screws is commonly recommended where metal-to-metal contact exists.

These alloy knuckle arms are a practical upgrade for E-MAXX owners seeking improved steering consistency and component longevity; confirm fitment and torque specifications with your chassis before extended use.
