Application Chart Single Tube

OVERHAUL
Single Tube Damper Design
The new HIPERMAX S series continue to employing the single tube structure.
The advantage of this structure is to be able to provide the gas and oil chamber separately, and then it allows to use of a large diameter piston. As a result, a quality and stable damping force is gained.
Inverted Shock Absorber (Strut)
・Large lateral forces are spread over a larger area increasing rigidity under high loads or with larger wheels
・Damper is attached to body side reducing un-sprung weight for improved handling
Dual PVS
The Pre-load Valve System, introduced in the previous MAX IV GT 20 Spec,S-Style L,S-Style C, created a remarkable difference to handling performance. This has been further refined to introduce “Dual PVS”.
High speed damping is reduced while keeping unnecessary movement to a minimum.
WR Needle: Wide range damping force adjustment mechanism
The improved shape of the needle expands the oil relief channel. Each step of the 30 step adjustment is now more prominent. Having softer adjustment options gives more options for street driving.
ADVANCED BUMP RUBBER(Evolution of Bump stop rubber)
For HIPERMAX S, a further improved “ADVANCED BUMP RUBBER” was developed which pursues further softness and also shorter variations deliver a wide range of options for a variety of cars delivers a natural and smooth experience
PNE Coating
HKS previously introduced SNOW EDITION versions to combat corrosion head on. The result of this development was PNE coating delivering 5x better durability compared to standard galvanizing
Strengthened Rubber Upper Mount
Strengthened rubber upper mount is able to absorb small body vibrations whilst tightening up the mount over stock. Revised cross sectional design and material composition balance comfort and performance
"KODAWARI" of Exterior
The aluminum top mount is chamfered by machining to enhance the beauty of the product.Delivering detail and quality which was not previously available through previous printing methods
Peace of mind with 3 years warranty
The internal structure of the HIPERMAX IV GT series has been reviewed in HIPERMAX S to deliver a 3 year warranty over the existing 1yr.
Extensive in house durability testing and development has resulted in improved correlation between test bench and real road data and in-house manufacturing allows for quality control of all components which provides the necessary evidence to deliver the 3yr warranty with confidence.

HIPERMAX S Core Technology

Dual PVS

Dual PVS

The Pre-load Valve System, introduced in the previous MAX IV GT 20 Spec, created a remarkable difference to handling performance. This has been further refined to introduce "Dual PVS".
High speed damping is reduced while keeping unnecessary movement to a minimum.

  • Compared to without PVS, shaft extension is more responsive improving tire contact with the ground.
  • Under fast compression, damping force rises quickly to absorb the impact energy from bumps.
  • Initial damping is effective under rebound to reduce bouncing and fast stabilization.
