I did the same when bought the QA1 for my HC. Quality is the same. Difference is the SFI certified one is torque tested by them and given the cert. I think the cert is required on the NHRA tracks or something.I went the route of a non-certified driveshaft. Figured the quality would be the same. Downside is that it will be April before testing it out.

On the QA1 website it looks like 08 is with SFI and 13 is not. Do the vehicle search and click on either DS. Then click on the part numbers tab. I don't see any other differences between the two but read up on it and call them if you still have questions.So does JJ-21208 or JJ-21213 have the SFI certification?
Thanks I ordered 21208 with SFI.On the QA1 website it looks like 08 is with SFI and 13 is not. Do the vehicle search and click on either DS. Then click on the part numbers tab. I don't see any other differences between the two but read up on it and call them if you still have questions.

Here you go...Thanks I ordered 21208 with SFI.
I do need to know the allen socket sizes (or any other sockets) for the install. It would be great if someone can chime in. So:
- Sockets to remove the stock driveshaft (transmission side and diff side).
- Sockets to install the QA1 driveshaft (transmission side and diff side).
