3Racing SAK-D6818/PU Rear Big Bore Aluminum Shock Absorber for Auper D6 Chassis, Purple Anodized Option  [SAK-D6818/PU]

Rear big-bore aluminum shock for Auper D6

This aluminum rear big bore shock from 3Racing, model SAK-D6818/PU, is a direct replacement-style absorber intended for RC-scale use with the Auper D6 family. It is offered in a purple anodized finish and designed to serve as an upgrade part that changes rear suspension response by providing a larger-diameter shock body and aluminum construction compared with standard plastic or small-diameter units.

The article focuses on compatibility, installation considerations, and the tuning role of the part: it replaces the stock rear shock assembly on Auper D6 chassis variants that accept the same mounting pattern, installs into the rear shock tower and lower mounting bracket using existing hardware, and participates in spring, damper and ride-height setup to alter handling balance. This description remains limited to RC modelling contexts and does not imply real vehicle use.

As an aluminum rear big bore option, the SAK-D6818/PU provides a change in damping feel and durability for hobbyists running Auper D6 chassis who want a metal-bodied shock with a distinctive purple finish; use it as part of a systematic damping and spring setup process to achieve the desired rear-end behaviour.
