Auper D6 Pulley Upgrade for Belt Tuning - SAK-D6809A by 3Racing  [SAK-D6809A]

Pulley upgrade for belt tuning on Auper D6

This aluminium pulley is a replacement component designed specifically for the Auper D6 drivetrain and identified by part number SAK-D6809A. As a direct-fit option, it serves as a maintenance spare or modest hop-up to swap out worn stock drivetrain pulleys.

Fitting is intended to use the factory mounting points on the Auper D6 layout. During installation, confirm shaft alignment, belt seating and tension, and check adjacent bearings for wear before final assembly.

For tuning, the metal pulley provides a stiffer option than many plastic parts, assisting in consistent belt tracking during setup without requiring chassis modifications.
