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

Titanium main shaft spacer for Auper D6

This is an RC-scale main shaft spacer produced by 3Racing 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 establishes the axial gap on the main shaft, helping to maintain correct gear mesh and bearing preload when assembling or servicing the Auper D6 transmission stack. Accurate spacing reduces play and supports repeatable setup during chassis tuning.

Installation notes: this spacer fits onto the main shaft in the location used by the stock spacer on Auper D6 kits, and it is intended to be used as a direct replacement part. During reassembly, confirm shaft runout and bearing seating before final tightening, and use appropriate thread locking where specified by the chassis manual. No special tools are required beyond common hobby hex drivers and basic assembly tools.

Materials and maintenance: titanium offers improved corrosion resistance and a good strength-to-weight ratio for small parts, but like all RC components it should be inspected for wear or damage during routine maintenance and replaced if any deformation is found.
