Auper D6 Titanium Main Shaft Spacer SAK-D6809C by 3Racing  [SAK-D6809C]

Titanium spacer engineered for Auper D6 drivetrains

This RC-scale main shaft spacer SAK-D6809C is designed for the Auper D6 platform. The part is a single-purpose spacer made from titanium to provide corrosion resistance and dimensional stability compared with basic alloy alternatives.

Role and tuning impact: the spacer sets the axial gap on the main shaft, helping to preserve correct gear mesh and bearing preload when assembling or servicing the Auper D6 transmission stack. Accurate spacing reduces endplay and supports repeatable setup during chassis tuning.

Installation notes: this spacer installs onto the main shaft in the same location as the stock spacer on Auper D6 kits and is intended as a direct replacement. During reassembly, check shaft runout and bearing seating before final tightening, and apply thread locking where the chassis manual specifies. No special tools are required beyond common hobby hex drivers and basic assembly tools.

Materials and maintenance: titanium offers improved corrosion resistance and a favorable strength-to-weight ratio for small parts; inspect SAK-D6809C for wear or deformation during routine maintenance and replace if any damage is found.
