Wow talk about old post but glade to see some using the search function! I have never owned a torsion diff but from all the reading I have read on US tracks more times then not they are not worth it. Now I have read on Euro tracks it helps but they normally have large swiping turns and not any really big or many jumps. Correct me if I am wrong someone as I can only go by what I have read. They cost to much for me to try them.
