Are 31 splines really that much stronger? I plan on replacing everything in my rear end and I was wondering if its really worth it to step up to the 31 spline. I plan on, some day to add amild hci set up with hopefully about 270- 290 range. thanks

Just a cruiser or will you be racing? I mean if you're gonna be replacing everything in the rear, go w/ the 31's.

I'm steppin up to 31's very soon.

Just a cruiser, not a DD.

If you are never going to exceed 300rwhp and never put slicks on then
no you do not need 31 spline axles.
If you are replacing the axles anyway, then I would go ahead and upgrade to 31's for peace of mine.

It also depends on what you are doing with you differential
If you are installing a "new" dif, and not rebuilding your old then go 31's
if you are just overhauling old one then stick with 28's

i would go with 31 spline

I use moser 28 splines, theres less rotating mass, and there super strong,
I'llsee how they handle over 600hp in a couple months
