Which Diff is "stronger"

[MikeW]

I am doing a SRA build. The car will be 85% street and at the drag track the rest of the time. I have found an Eaton Posi (31 spline) for sale local. I had my mind set on a True Track since there are no clutches to "wear" out. The local seller tells me that the Eaton posi is stronger than the True track ????? I have read just the opposite when I looked around on the boards last night.



I only wanna try and do this once so which would hold up the best. The car puts down 630RWHP and will not be driven in the rain unless caught out.



Thanks,

mike
