Additional Product Features
Single Tube
HKS has been focusing on utilizing "single tube" technology since beginning development on suspension. Single tube is the natural choice for HKS because high performance of the single tube has been proven through use by many racing and luxury cars. Singletube suspension the natural choice when product quality is prioritized over everything else. Optimum dampening force, stability and structural rigidity, responsive and reactive setup and superior ride comfort under many different road conditions are all made possible through the use of single tube dampers
Natural "G" Based on Dynamics
Maintaining the stock (genuine) design structure. Adjustable suspension has the advantage of changing vehicle height to suit an owner’s preference; however, the height adjustment range and stroke length are difficult to maintain. The stock shape type suspension allows more stroke for precise settings; premium ride quality under various road conditions is guaranteed.
By utilizing the stock suspension structure, spring length can be maintained whilst being able to cancel the bending force applied during suspension stroke compared to coilover type designs. This allows full utilization of the spring and damper's performance. In order to achieve both a high quality ride and appropriate low stance, it is natural from the perspective of chassis dynamics to maintain the design structure of the stock damper.
Quality from the Materials Up
The spring material is of the highest grade, which exceeds the general standard delivering superior durability.
High Rigidity Not Comparable with Conventional Dampers
The rigidity of the mounting bracket and case have been greatly enhanced. With strut type suspension, the damper holds the vehicle weight; therefore, by combining with an inverted type damper, the handling road holding and stability during braking are improved, and a premium ride quality is provided.
PNE Coating for Long Life Performance
HKS suspension series utilize PNE coating which is proven in snowy regions and the coasts to maintain premium ride comfort. This special surface coating provides 5 times better durability over standard galvanizing.
Approach to the Perfect Setup
Even if the base design is excellent, without a proper understanding of each vehicle’s characteristics and technology to optimize setup, the advantages of the base design cannot be fully utilized. HKS conducts many tests under various conditions to ensure the high quality of ride, handling, and driving stability. Various vehicle specifications such as larger tires/wheels are taken into the consideration when testing the products. HKS never compromises to make our customers satisfied with our product under various environments.
Internal Parts Defines Setup
Valve shims are a key part in defining the suspension feeling. HKS uses a large variety of shims compared to many other manufacturers to create the variety of dampening needed. A small difference to the dampening force can make a noticeable difference to the driver. HKS performs multiple tests to perform these small changes to create an uncompromising premium ride quality.
