Conventional wisdom would tell us the 489 is the strongest 8 ¾ third member, then the 742, and the 741 is the weakest. Who here has ever broken a 741 on the street using street tires?
I'm asking because I have been passively looking for a third member with a 3.73 or 3.91 ever since I had the 46rh OD installed, and I have noticed people tend to value 489 third members like they're made of gold. I have been beating the ever living hell out of my car's the 741 diff (3.23 Sure Grip) for going on 25 years and I have never even had it apart. And none of my local Mopar buddies have ever broken a 741 on the street. They've got stories about breaking every diff you could imagine at the racetrack, but with sticky tires and a prepped track you can break almost anything.
So, is the 741 actually weaker than the others or do we just think it's weaker because it should be weaker?
