Code No. 80300-AT036
■Features
- The stylish-looking Crown Sport comes with factory 21-inch wheels, and by combining the low-down style with the driving comfort proposed by HKS, it is transformed into a sporty look, comfortable yet firm ride.
- With a focus on passenger comfort, the settings were made with an emphasis on quietness around the rear and suppression of the bouncy feeling felt with the factory model.
- In addition, by suppressing unnecessary movement of the body, HKS provides a ride that is gentle on passengers and worthy of the Crown Sport for the driver.
- This product is for vehicles without electronically controlled dampers only. It is not compatible with vehicles with electronically controlled suspension.

*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.

■Developer’s comments
- The bouncy feeling and sudden stiffness felt with the OEM suspension have been reduced, improving driving stability.
- We prioritized quietness and designed the rear to use the stock upper mount.
- By modifying the stock rear bumper rubber, we have reduced the frequency of bump contact for a comfortable, sporty ride.
- The damping force can be adjusted in 30 steps, ensuring a wide range of adjustments, allowing you to adjust it to your liking, from relaxed city driving to sporty driving.
■HIPERMAX S Technology
Preload valve system
We have adopted a preload valve system.
It cuts the damping force at high speeds and suppresses unnecessary movement
It provides a comfortable ride without any bumps.
Wide-range damping force adjustment mechanism
By evolving the shape of the jet needle, the range of damping force adjustment has been expanded compared to conventional products.
It can be used at any stage.
3-year/60,000km high-durability specification Advanced tribology has achieved high durability and low friction.
Improved ride comfort and handling.
