The stock 8.8 is fine, unless you are doing a huge torque converter with a trans brake or a stick car launching at the red line.
Then you might need the DSS axles, the kind with the larger outer

Now I run DSS axles on my mostly drag racing car.
If you want to look fancy, buy the special differental cover, those look cool.
