Overview
Transfer cases are typically for 4WD/AWD applications. Correct fitment requires more than year, make, and model.
Key identifiers
- VIN
- Tag number (often from dealer or GM Parts catalogs)
- Shift motor type: electronic button vs manual lever
- Output shaft length / wheel base when applicable
Tip
One tag number can match multiple catalog lines — always confirm shift motor style with your installer or dealer.
