It houses a 3.55:1 hypoid ring and pinion set to provide final drive gear reduction in heavy-duty trucks. It's a complete drop-in unit that eliminates the need for a core return, commonly used to replace a worn or damaged carrier in tandem drive configurations for the forward rear axle (front rear).
