The 3Racing SAK-D626B rear bulkhead is engineered to reduce rear chassis deformation and support consistent suspension geometry during competitive running. Designed with fit and repeatability in mind, it assists in maintaining predictable handling when fine tuning setup or changing surface conditions.
As part of a race setup, this bulkhead helps control rear flex that can mask suspension adjustments, allowing more precise tuning of damping and roll characteristics. The component aligns with Sakura D6 mount points to preserve suspension pick-up locations and ride height settings.
For reliable results, install using a staged torque sequence and inspect mounting interfaces for wear after heavy sessions. Periodic verification of thread condition and fastener integrity will protect alignment and ensure consistent performance across events.
