Tech Note 1: Narrow vs Wide 
This Bearing fits a number of New Process chain drive transfer cases in Chevy, Dodge, and GMC 4x4 vehicles. However, it does not fit all years or even all cases in one model year as some transfer cases used this narrow bearing and some have a wider bearing. This QU50874 narrow bearing is approximately 5/8" (16mm) wide, the wide bearing (QU50873) is approximately 15/16" (23.7mm) wide. These two bearings are NOT interchangeable! Please see the Application section below for specific fitment information that we have verified.
