This SCX021 alloy front knuckle arm is a CNC-friendly style replacement for the Axial Racing SCX10 Honcho front hub and steering pivot, supplied as a 1pr set for hobbyists seeking improved pivot stiffness. It is intended for scale RC maintenance and tuning applications.
Fit and function: the machined knuckle arm replaces the factory item to recover steering geometry and alignment on SCX10 Honcho chassis. Standard installation involves wheel and linkage removal, fitting the new arm pair, and validating steering arc and camber to match your suspension setup.
Installation notes: maintain the original hardware pattern to avoid hub or hex alteration. After installation verify clearance to suspension links and drive shafts and set pivot fastener torque to eliminate play while allowing free articulation under load.
Tuning role: a stiffer alloy knuckle reduces pivot deflection and helps maintain consistent steering inputs across technical crawls, improving line control. Balance component stiffness with expected trail impacts to manage failure modes.
