In retrospect, I SHOULD have gone to 31 spines when I had my 4:10's put in.

I pulled 1.60-1.65 60fts for 3 years and never broke one. We are talking literally hundreds of passes.
I upgraded to 31 spline axles only because my pinion shaft welded its self to the planetary gear and since I had to take it apart to fix that I went ahead and upgraded.
I doubt you would ever break one with the HP you are making with an auto.
If you decide to spray it however I would upgrade just to be safe.
