Z31 Anti-Sway Bar Differences
There are two different styles of front anti-sway bars used on USDM Z31. From 1984-1986 Nissan used a horizontal mount front anti-sway bar where the end link is a long bolt with spacers. In 1987, Nissan changed to a vertical mount swaybar. There was three front Anti-Sway Bar sizes available on the 1984 to 1989 USDM 300zx. The following chart will provide the models and size of the sway bar front and rear.
