The Pro Max has model-specific battery, display and USB-C port procedures, plus separate camera and microphone guides.
What to check before buying
Battery and display
iFixit documents adhesive materials for both battery and screen work. The larger chassis uses Pro Max procedures rather than the smaller Pro guides.
Ports and imaging
A USB-C port assembly, camera modules, LiDAR sensor and microphones are separately documented. These are different repair scopes even when faults appear after the same drop.
