Tein's front pillow ball (spherical bearing) upper mount is designed for each individual model of any vehicle. By retaining the positioning design of upper spring and shock absorber close to manufacturer's standards, Tein's pillow ball upper mount keeps height change to the minimum and maintains the stroke center. The rubber bush is replaced with a pillow ball which eliminates the load input compliance and reduces the change of alignment to improve the grip of the tire. Ultra duralumin A2017S-T4 is used for the upper seats and the adjusting plates uses anodized aluminum to provide maximum strength and durability. The camber angle is adjustable from the front which creates wide varieties of different suspension settings according to the road and tire condition. High tension material S45C is also used for serration bolts. With the long bolt design, it can be easily mounted and gives enough thread for the strut tower bar to be fitted.
