Axial SMT10 Knuckle Arm Set 6061-T6 - MJ021 by GPM  [MJ021]

Precision front knuckle arms

This knuckle arm set is engineered for the Axial SMT10 family and is supplied as model MJ021. Machined from 6061-T6 aluminium, the components are intended as stronger aftermarket replacements for plastic arms, improving stiffness and resistance to wear while maintaining the intended steering geometry.

The kit features hardened king pins designed to interface with Delrin bushings at the bearing faces, reducing play and keeping steering movement smooth. The hardware set provided supports mounting and stabilisation of the CVD arrangement to preserve steering input fidelity without changing geometry ratios.

The original parts list remains the reference and includes king pins, stainless steel 3x18 round head screws, 3mm silver lock nuts, and manual reference AXA31316. These parts are sold as upgrade replacements and are not OEM components.

Fit MJ021 knuckle arms to reduce movement around the CVD and achieve a crisper steering feel on SMT10 Grave Digger conversions; double check mountings and torque values before running.
