In this thread we will discuss 28 to 31 spline conversions

[slowmkviii]

99 Cobras have 28 spline, and 01 up cobras have 31 spline...PERIOD!!!

I did some looking you are probably correct I think I just had bad luck
both people I talked to when I bought my diff said thay had an 01 diff with the 28 spline Now I think they were wrong and you are right
sorry I just had bad info

Not a problem at all. Most people don't know that ford switch between 99 and 01. Prolly because those two vehicles didn't receive any where near as much attention, as the 03/04 cobras did.

hes right.


ALL explorers have 31 spline. IRS or not. ranger 8.8s are 28 spline EXCEPT for rangers equipped with the torsen diff (FX4 level 2)

when it comes to IRS 8.8s in cars...all are 28 spline up until 2001 cobras. 99 is the only cobra IRS with 28 splines
