The GPM MJ021 front knuckle arms are CNC machined from 6061 T6 aluminium to provide enhanced rigidity with controlled elastic response for the AXIAL SMT10. These parts are engineered to stabilise the CVD interface and refine steering inputs while retaining resilience under load. Precision king pins and delrin bushings are included to ensure minimal clearance and consistent joint articulation, supporting reliable handling and longer service life.
