Check before ordering: many transfer cases changed parts by year, drive (2WD/4WD) and version. Confirm your unit by its ID tag. ID tag is on the REAR of the transfer case near the rear output. The tag model line reads 261/263 plus HD or XHD; it is the fastest fit key. Call us with your tag and VIN if unsure.
