Transfer case adapters are what let a builder choose a transmission and a transfer case independently instead of accepting whatever pairing the factory offered. The adapter indexes the case to the transmission housing and matches the output shaft, so torque is transferred on center with no improvised spacers or slotted mounting holes.
