Product Description

A new standard of "Driving Comfort" aims for comfort in the ride as well as the peace of mind produced by handling performance and drivability, going beyond just ride comfort or handling performance. A perfect balance that meets all of the demands of street driving.

Starting in 2021, the three current MAX IV GT series will be replaced by the HIPERMAX S. Since the release of the MAX IV GT nine years ago, HKS has created new technological advancements. It will be a new series that possesses the qualities of the three traditional model types and has evolved due to its damping force characteristics, robustness, and beauty. The most comfortable ride in HKS suspension history is provided by the HIPERMAX S series.

HIPERMAX S Technical Details:

Dual PVS

We 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 major improvement in ride comfort without affecting the driving performance.

Wide range damping force adjustment mechanism
The improved shape of the Needle jet expands the range of damping force adjustment. This makes is 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 ride comfort at the same time which cannot be achieved with general hydro bump stop rubber.

Low friction technology
With advanced tribology technology, we have achieved even higher durability and lower friction than conventional products. This technology contributes to improved ride quality and handling performance.

3-year warranty
Compared to the one-year warranty period of the conventional MAX IV GT series, the HIPERMAX S Series has a three-year warranty due to optimized internal parts and quality improvement.
