basic information
There are two types of leaf springs: vertical and horizontal. We can achieve weight reduction by replacing existing vertical leaf springs. Additionally, horizontal leaf springs can secure battery space for new EV platforms. They are being adopted in EV platforms currently under development by European and American automakers. If there are similar projects in Japan, please contact us.
