Check before ordering: many transfer cases changed parts by year, drive (2WD/4WD) and version. Confirm your unit by its ID tag. Read the cast number on the case and the BorgWarner tag on a case bolt (starts 44-xx-xxx). BW4401 (GM K3500 1989/90-2000, manual lever): check for a separate CENTER PLATE between the front and rear case halves - no plate = BK1356 parts; plate = BK4470 parts. Call us with your tag and VIN if unsure.
