Are you looking for the perfect way to connect your 1990-1997 NA Mazda Miata shocks with 1999-2005 NB Mazda Miata shock hats? You've come to the right place.
Our USA-made, custom-built M12 shoulder nuts are used in our Mazda Miata Shock Mount Systems and are designed to thread onto Koni Sport shocks which have an M12 threaded shaft end.
These shoulder nuts allow you to use 1990-1997 NA Mazda Miata shocks with 1999-2005 NB Mazda Miata shock hats, specific to Koni Sport shocks. NA Miata shocks have a shorter shock body and less length on the threaded portion, which makes installing the NB shock mounts difficult as the bump stop doesn't allow the threaded portion of the shaft to protrude the shock hat like the NB shocks would. These shoulder nuts will plunge into the shock hat and allow you to connect with the NA shock shaft.
- Will NOT work with 1999-2005 NB Miata Shocks!
