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

Front knuckle arm for SCX10 Honcho

This GPM SCX021 alloy front knuckle arm is a scale RC replacement part produced for the Axial Racing SCX10 Honcho platform and sold as a 1pr set. It serves as a direct swap in the front steering and hub area, intended for hobby-grade crawlers and trail rigs rather than any real vehicle application.

Fit and function: the component replaces the stock front knuckle arm on Axial SCX10 Honcho chassis to restore steering geometry and maintain wheel alignment. Install typically involves removing the wheel hub and steering linkage, swapping the knuckle arm pair, then reassembling while confirming steering throw and wheel camber remain within expected ranges for your build.

Installation notes: use the same hardware pattern as the original part to avoid modifying the hub or hex. Check clearance against the front suspension and drive shafts after installation, and verify tightness on pivot screws to avoid play while keeping movement free under load.

Tuning role: upgrading to an alloy knuckle arm provides a stiffer mounting point that can reduce flex at the steering pivot, which helps maintain consistent steering response during low-speed crawling and technical trail sections. Balance stiffness with fragility expectations depending on your driving style and trail conditions.
