Pursue a comfortable ride and more enjoyable handling performance.
HKS has integrated and renewed the three existing MAX IV GT series coilovers into the HIPERMAX S! These coilovers shares characteristics with all three of the conventional models and has evolved new damping force, durability, and beauty characteristics. The HIPERMAX S series coilovers offer the best ride in HKS suspension history.
Features:
- Single Tube
- 30 Levels of Adjustable Damping
- Adjustable Shock Body Length
- Special Oils
- PNE Coating
- Dual Pre-Load Valve System
- Aluminum Bracket
- Upper Rubber Mounts

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.
