Axial SMT10 Compatible Knuckle Arms 6061-T6 - MJ021 by GPM  [MJ021]

Front steering knuckles in 6061-T6

This knuckle arm set is intended for the Axial SMT10 chassis and is identified as model MJ021. Fabricated from 6061-T6 aluminium, the parts are offered as tougher aftermarket replacements for factory plastic arms, helping maintain accurate steering geometry on scale stadium trucks.

Hardened king pins work against Delrin-style bushings at the bearing faces to trim unwanted movement and keep steering action smooth. The supplied hardware is arranged to support mounting and to add CVD stabilisation without modifying the original steering angles.

The component list supplied in the original description remains the reference: king pins, stainless steel round head screws (3x18), 3mm silver lock nuts, and manual AXA31316. Use these items as upgrade parts only and verify fitment prior to use.

Fit MJ021 knuckles to tighten up play around the CVD and deliver a more direct steering feel for SMT10 Grave Digger projects; always recheck mounting torque to avoid loosening under use.
