AXIAL SMT10 Aluminum Front Knuckle Arms 10pcs by GPM MJ021  [MJ021]

Aluminum front knuckle arms

This RC-scale front knuckle arm set is designed for the Axial SMT10 platform and supplied by GPM under model MJ021. Machined from 6061-T6 aluminum, the components are intended to replace stock plastic arms where increased stiffness and wear resistance are desired while keeping precise steering geometry for scale stadium truck setups.

The assembly includes hardened king pins designed to work with Delrin bushings at the bearing interface to reduce play and maintain smooth steering motion. The hardware set provided supports mounting and CVD stabilization to assist steering input fidelity rather than alter steering ratio or geometry.

Included items and reference numbers are provided in the original parts description: king pins, stainless steel round head screws (3x18), 3mm silver lock nuts, and manual reference AXA31316. These parts are intended as RC-scale replacements and upgrades only.

Use these knuckle arms to reduce play around the CVD and to provide a firmer steering feel on Axial SMT10 Grave Digger builds; verify fit and fastener torque against your chassis manual before running.
