The 3Racing SAK-A583 Aluminum Transmission Ball Bearing Housing Kit is produced for the Sakura Advance 21 chassis to replace the fragile plastic housing. The aluminium construction improves structural stiffness and supports smoother gear engagement during spirited runs.
Aluminium resists wear better than plastic and keeps mount points stable, resulting in more predictable driveline behaviour. The SAK-A583 helps lower the chance of gear misalignment under load.
Designed for direct fitment to Sakura Advance 21 mounting locations, the kit installs quickly with standard tools. Check bearing seating and fastener torque after installation to ensure correct operation.
