For those wondering how the new re-designed stearing dampener looks like, here is some pictures, it seems lighter and with a smaller diameter. Only time will tell if it’s more effective.

New part number and made in the USA...

Looks like Hitachi USA makes it.

old one made in Mexico, I don’t know who the manufacturer is, so if you getting yours changed on the new TSB make sure it looks like the new one.
