Super 30 dana 30 kit?

Do all super 30 chromo shaft kits just bypass the vacume disco? ie go from 2 pieces to a one piece axel up to the hub. Does anybody sell a plate to just cover up the hole if your not using the vacume actuation?

Is there any real disadvantage to not using the vacume disco and just putting in a one piece shaft?

Yes, all aftermarket CrMo kits delete the vacume disconnect. If you talk to the vendor you buy from, you can get the kit with the plate to cover the vacume disco, you also have to change a seal. I know the alloy-usa 27 and 30 spline kits offer that, I'm sure superior probably does as well.

The only disadvantage is if you have really bad front driveline angles or a worn out front driveshaft, you'll start to get vibes..

..but those are both problems you should be addressing anyways.
