Bottom Case

Description

This A3403 Bottom Case for 2024 MacBook Pro 16″M4 Pro replaces the lower chassis, restoring structural stability and alignment between internal components. The part secures ports, connectors, and internal hardware while addressing damage from drops, warping, or wear. Replacing this case ensures proper closure with the top housing and maintains device durability during daily use.

  • Protects internal logic boards and battery packs from physical impacts by offering a rigid outer metal shield.
  • Fixes warped or twisted laptop enclosures to allow seamless alignment between the lower body and top screen lid.
  • Maintains standard airflow distributions through accurately placed exhaust vents to keep working temperatures low and stable.
  • Replaces dented aluminum shells, missing support feet, and scratched lower housing panels to return a smooth flat surface.
