Hey I went to a shop and told them that I want to switch axles because I have the stock ones and they, are getting torn up because of the power of my car. So one guy told me to go with the Moser 28spline he said that they are stronger than the stock ones. But I thought switching too 31 spline would be better for me since I am already pushing 380 rwhp and I plan On getting a charger added later on but he said if i would to do that then I need to switch out my traction lock since my posi is set up for 28 spline. Do you guys think is worth spending the extra money and switching to 31 spline or do you think those 28 spline's would work.
