The 3RACING SAK-D6823A rear upper arm bolt is produced to provide a precise, repeatable mount point for Auper D6 rear suspension. It is intended to keep alignment and articulation consistent under competitive running conditions.
Aluminium delivers a favourable strength to weight ratio for suspension fasteners where reducing unsprung mass is desirable. When planning a setup change, factor in the bolt material relative to your chosen arm design and pivot tolerances to preserve predictable handling.
Fit the bolt using the correct torque sequence and inspect mating faces for burrs or deformation that could affect preload. Regular inspection after aggressive use will help you detect wear early and maintain consistent suspension geometry.
