31 spline question

[jeffstanggt04]

if i want to go to 31 spline axles will i have to change my whole differental or what

yes you will. need a 31 spline differential to go with 31 spline axles. this is one part of the car where you can't mix and max parts. then again, you'll be strengthening you rear end a bunch

yup.. and it just so happens the differential costs more than the axels

Yes you will need a 31 spline carrier. Here's my Eaton 31 spline as compared to the Stock 28 spline.
