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

SAK-D6809C titanium spacer tailored for Auper D6

This RC-scale main shaft spacer SAK-D6809C is intended for use with the Auper D6 platform. It is a single-purpose titanium spacer that offers better corrosion resistance and dimensional stability than typical alloy alternatives.

Tuning effect: the spacer fixes the axial gap on the main shaft so gear mesh and bearing preload remain correct during assembly and setup. Consistent spacing reduces drivetrain play and helps with repeatable tuning sessions on the Auper D6.

Fitment tips: the spacer fits where the stock spacer sits in Auper D6 kits and is designed as a direct replacement. During reassembly, confirm shaft runout and that bearings are fully seated before final torque, and apply thread locking if the chassis manual directs. No special tools beyond normal hobby hex drivers are required.

Maintenance: titanium combines corrosion resistance with good small-part strength-to-weight, but inspect SAK-D6809C regularly and replace if you find any bending, scoring, or deformation.
