Dual PVS

HKS evolved the existing preload valve system to the dual preload valve system to suppress the generation of unnecessary damping force during higher piston speeds. This provides a major improvement in ride comfort without influencing the drivability performance.

Wide Range Damping Force Adjustment Mechanism

The improved shape of the Needle jet expands the range of damping force adjustment. This makes it possible to handle driving on a wider range of stages.

Evolution of Bump Stop Rubber

A new shape of bump stop rubber reduces the body roll and achieves increased ride comfort at the same time. Which cannot be achieved with the general hydro bump stop rubber.

Low-Friction Technology

With advanced tribology technology, HKS has achieved even higher durability and lower friction than conventional products. This technology contributes to improve the ride quality and handling performance.

3-Yeay Warranty

Compared to the 1-year warranty period that the conventional MAX IV GT series had, the HIPERMAX S Series offers a 3-year warranty due to the optimization of internal parts and quality improvement.
