Code No. 80300-AT031
- HIPERMAX S maintains the excellent driving performance of the stock suspension while improving driving stability in pursuit of driving comfort.
- The reason we were able to achieve ride comfort superior to the stock version with the lowered suspension is due to the suspension technology that HKS has cultivated over many years and the use of high-quality in-house parts.
- Due to differences in body and vehicle weight, there are differences in the ideal suspension specifications, so this is a "specification for Alphard 2WD vehicles".
- It possesses the versatility to cater to daily commuting, weekend driving, and sports driving.
- It comes with a 3-year warranty and can be overhauled. We also provide entire after-sales support. You can use the product for a long time.

*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.

Point
The all-new Toyota Alphard and Vellfire (40 series) feature improved factory suspension tuning compared to prior series. Our product was developed to keep the features, and also lowered the vehicle height to transform it into an impressively stylish appeal.
The car body strength and weight are completely different in each model and grade, but we also did fine-tuning by making many calculations and conducting long-term test runs on various roads to make the spring rate, damping, bump rubber, and gas pressure perfectly suited for the car to provide the best ride comfort.
(This product is exclusively developed for the Toyota Alphard and Vellfire HYBRID System 2WD vehicles. Not compatible with for 2WD vehicles equipped with Side lift-up tilt seat.)
As a result, we successfully improved the driving stability during high-speed driving and kept the riding comfort the same as with the factory suspension. We also further decreased the unpleasant micro-vibrations.
It allows you to feel comfortable in all seats, even when the vehicle is fully occupied with passengers.
