These rear ends are from a 2001 Mack truck. I will cut the frame where the blue tape is if you are interested in the complete set up. Gear ratio is 5.02 and they have abs sensors, according to VIN tag they have a capacity of 23,000 pound each. I not an expert in these rear ends but as far I can tell they are Hendrickson HN or CRD (I don't know how to tell the difference). Location is Minot North Dakota and I have a way to load. $1,800 cash please. Also selling the front axle off this truck also (in another post).
