Made for the Sakura M4 platform, the 3Racing Aluminum Bulkhead (SAK-M4S45) replaces weaker stock components to add toughness and precise fit. This upgrade helps lock in suspension geometry so setup changes behave predictably.

Stronger Aluminum Construction

This bulkhead uses a machined aluminum profile to resist flex under load, giving a more consistent chassis feel compared with standard plastic parts. Improved rigidity helps the suspension maintain correct alignment during cornering and hard acceleration.
