A durable PNE coating ensures long-term resistance to wear and corrosion, and the kit is backed by a three-year warranty for added peace of mind.

Dual PVS

• HKS has developed a dual preload valve system to replace the conventional preload valve system, effectively reducing unnecessary damping force generated at higher piston speeds. This advancement delivers a significant improvement in ride comfort without compromising overall driving performance.

Wide Range Damping Force Adjustment Mechanism

• The redesigned Needle jet increases the available range of damping force adjustment, allowing the suspension to adapt to a broader variety of driving conditions and road surfaces.

Evolution of Bump Stop Rubber

• A newly engineered bump stop rubber minimizes body roll while enhancing ride comfort, providing benefits that standard hydro bump stop rubber cannot achieve.

Low Friction Technology

• Through advanced tribology technology, HKS has achieved greater durability and reduced friction compared to conventional designs. This contributes to improved handling performance and overall ride quality.

3-Year Warranty

• The HIPERMAX S Series is supported by a three-year warranty, made possible by the optimization of internal components and enhanced quality control.
