Tein's pillowball (spherical bearing) uppermount is designed for each individual model of the vehicle. By retaining the positioning design of the upper spring and shock absorber (damper) close to the manufacture's standards, Tein's pillowball uppermount keeps height change to a minimum and maintains the stroke center.

• The rubber bushing is replaced with a pillow ball which eliminates the load input compliance, reduces the change of alignment to improve the grip of the tire.
  *NMB's (The world's top spherical bearing manufacture) pillowball is used.
• Ultra duralumin A2017S-T4 (aircraft material) is used for upper seats and adjusting plates with anodized aluminum to have maximum strength and durability.
• For the McPherson strut suspension (only for front) models, the camber angle is adjustable. This creates wide varieties of different suspension settings according to the road and tire conditions.
• High tension material S45C is used for serration bolts. As it is already inserted with high press, installation time has been completely reduced. With the original long bolt design, it can be easily mounted and gives enough thread for the strut tower bar to be fitted.
