You know alot of what twists axles is hard turning with a spool (especially with sticky tires)and not the launches .I have a spool in my Dart race car with a 35 spline mosier spool and axles and i make 3 point turns out of habit when they are sharp .Lesson learned from driving other cars with spools on the street .I broke many axles in 9 inchers in streetrods just daily driving with a spool till ifigured out what i was doing wrong.Its the drivers side that will usually break or twist with a spool and sharp turns .BTW i pull the axles out of my 8.75 in the Dodge once a season to look and they still look new ...
