The SAK-D6805/BU from 3Racing is an aluminum steering rack finished in blue anodizing and made to replace the stock steering assembly on Auper D6 car kits. It occupies the original rack mounting points while offering a metal alternative to the kit's plastic parts.
Performance notes: the metal rack cuts down on compressible sections in the steering linkage, helping to stabilise toe and steering throw changes during fine setup work. This makes geometry adjustments more predictable when dialling in handling or swapping out an aging stock rack.
Fitting guidance: remove the factory rack per the kit instructions, check mounting hardware and linkage for wear, then install the aluminum rack aligned with the servo spline. After fitting, confirm steering endplay and thread engagement at the linkage joints, and apply thread locker if preferred for your build.
A direct aluminum replacement for Auper D6 kits aimed at hobbyists seeking reduced steering flex and more consistent setup outcomes.
