Front Knuckle Arm Alloy SCX021 for Axial SCX10 Honcho 1pr by GPM  [SCX021]

Replacement alloy knuckle for SCX10 Honcho

This SCX021 alloy front knuckle arm is a 1pr aftermarket replacement for the Axial Racing SCX10 Honcho, aimed at hobbyists repairing or tuning scale crawlers and trail rigs. It replaces the factory front knuckle arm at the hub and steering pivot.

Fit and function: the arm is a direct swap into the Axial SCX10 Honcho front hub to recover steering geometry and keep wheel alignment stable. Typical swap steps include removing the wheel and linkage, replacing the knuckle arm pair, then checking steering arc and camber for the installed setup.

Installation notes: keep the stock hardware pattern to prevent hub or hex alteration. Once installed, verify clearance with suspension components and drive shafts and set pivot screw torque to eliminate play while retaining smooth articulation.

Tuning role: alloy knuckles stiffen the steering mount which can reduce pivot flex and help keep wheels tracking during slow technical sections. Choose upgrades that fit your driving style and trail exposure to manage durability trade offs.
