where can i get 31-spline axles? can i get them from the junkyard? are they expensive? im getting a 03 cobra differential and i dont want to mess with the gears inside it. so i want to just get the axles to make it work. am i correct in my thinking? will this work? thanks fellas

I have not seen any 31 spline half-shafts that fit the SC. I remember some talk about having some made, but never heard the end of it. You might contact Raxles (www.raxles.com) and see if they are making any.

I believe the ones on the Cobra will be too short for the SC. I actually have not seen a half-shaft break at the differential end on an SC. Too bad you could not get a 99 Cobra pumpkin with the 28 spline diff.

I think GKN will be making them soon. But you will need a 31 spline differential from a 01-03 Cobra. .

Take a look at this thread going over on TCCoA, I believe it's the only potential source for 31-spline half-shafts for our cars at this point.

I posted about this awhile back and they said they would get back to me when teh SC version was complete..Of course they havnt gotten back to me yet..And they are not complete...Most of us with high power cars will need new axles as well as a new diff so its a perfect combination..Unfortunately the outer splines are still 28..Same as the Cobras

You can't use it unless you can find some halfshafts, and at this time nobody makes them.

You'll also need to change the pinion flange. The '03 Cobra driveshaft uses 1350 joints, and your driveshaft won't bolt up to the flange.

If its only teh differential you will need to waittill they make those 31 spline halfshafts..If its the whole pumpkin just as Daug stated..You will need new shafts and driveshaft flange
