3Racing Sakura D4 Rear Bulkhead Cover Race Upgrade - 3Racing SAK-D4811/BK  [SAK-D4811/BK]

Race-Focused Rear Bulkhead Upgrade for Sakura D4

The 3Racing Sakura D4 Aluminum Rear Bulkhead Cover is designed to increase rear chassis rigidity while maintaining precise alignment with existing mounting points. Precision-machined aluminium provides stable mounting for suspension and drivetrain components, helping to reduce variables that affect lap-to-lap consistency.

Track-Level Benefits of an Aluminium Bulkhead

Upgrading to a machined aluminium rear bulkhead improves torsional stability and limits flex around the rear assembly. For racers that tune suspension and diff settings, this 3Racing component helps the chassis respond more predictably to setup changes and surface variations.

Practical Setup and Maintenance Guidance

Fit the 3Racing Aluminium Rear Bulkhead Cover using a cross-pattern approach to tighten fasteners evenly and avoid distortion. Monitor screw torque after competitive sessions and inspect contact points for wear. The part integrates with standard Sakura D4 hardware and supports common tuning adjustments.
