Introducing the latest technologies to suit modern drag racing requirements

The drag suspension designed based on HIPERMAX II Drag Suspension.
Parts such as 300mm long spring, helper spring, etc. are selected for each vehicle model to maintain sufficient stroke amount and traction.
The shock-body length adjustable type is chosen to widen the vehicle height setting range and stroke distribution.
This drag suspension guarantees its performance in a drag race.

Single Tube Damper Design

The single-tube damper design was selected from well-established HKS suspension.
Its large diameter piston contributes an excellent response and traction assurance.

Dust Boot

Protect the shaft from the flying stones.

PNE Coating

Using this special surface coating provides 5 times better durability over standard galvanizing. This prevents build-up around the threads of the adjustment areas allowing for easier height adjustment.

Pillow Ball Upper Mount

With the pillow ball upper mount, the shock absorber detects fine movement and generates accurate damping force from the beginning of the stroke. Unnecessary movement is reduced and stable driving is possible.

New Design Needle

A newly designed needle has been utilized to adjust the damping characteristics of the very low speed and middle and high speed dampening to pursue the linear change across the entire speed range.

Reduction of Unsprung Weight

In order to reduce unsprung weight, bracket, ride height adjusters and lock nuts are made from aluminum. (Not for all vehicles)

30 Step Damping Force Adjustment

30 levels of dampening adjustment allow fine tune adjustment for each tire and course conditions.

*1. Height from road surface to fender arch.
*2. Height at factory is the data tested at HKS with the setting of Full Kit. (HKS' recommended setting.)
*3. Adjustable range (However, the lowest value may not be road legal.
Even within the adjustable range, car body, arm etc. may contact. In such case, it will be hard to drive.
Damper oil leakage or any other problems caused by low ride height setting from the factory setting will void the warranty of the product.)
*4. Drivable range that there is no contact of car body or arms etc. (However, change of tire/wheel size may cause a problem.)
Caution). Actual data depends on each vehicle.
