Axial SCX10 Honcho Alloy Front Knuckle Arm SCX021 Replacement by GPM  [SCX021]

Front knuckle arm replacement for SCX10 Honcho

This SCX021 alloy front knuckle arm is an aftermarket 1pr replacement intended for the Axial Racing SCX10 Honcho platform, intended for scale RC maintenance and tuning rather than any road vehicle use. It fits in the front steering and hub area as a direct swap to the original arm.

Fit and function: the component restores steering geometry and wheel alignment when installed on the Axial SCX10 Honcho chassis. Installation commonly requires removing the wheel hub and steering linkage, fitting the new knuckle arm pair, then verifying steering throw and camber to suit your build settings.

Installation notes: retain the original hardware pattern to avoid modifying the hub or hex. After assembly, confirm there is no interference with front suspension parts or driveshafts and tighten pivot screws to remove play without restricting articulation.

Tuning role: using an alloy knuckle arm stiffens the steering pivot and can reduce flex, improving steering consistency in slow technical crawling. Factor in the increased stiffness when planning durability for rough trails.
