Yep, the nerve manifolds have always, since day one, been aluminum. That is why nerves don't have shoot down or FSDO, unlike some shockers.
-The NDZ manifold doesn't really help that much, as stated above it is just really for if you are worried about stripping yours, which probably won't happen. I was going to get one, just because it is an upgrade, but it will be the last thing I buy for mine, because it doesn't really help that much.
