HKS HIPERMAX S Coilovers for RZ34 Nissan Z

HIPERMAX S has been innovatively improved in terms of its damping force characteristics, longevity and aesthetics to provide an ideal experience for those driving the new FAIRLADY Z.

After 9 years since the launch of MAX IV GT, HKS has incorporated newly developed technologies into what was originally three existing series to ensure that HIPERMAX S offers unparalleled durability, damping force characteristics and a sleek aesthetic – making it the best ride in all of HKS suspension history.


  • 30 Levels of Adjustable Damping
  • Single Tube
  • Shock Body Length Adjustable

Dual PVS

  • The existing preload valve system was improved by HKS to create the dual-preload valve system in order to prevent excessive dampening forces from being generated at higher piston speeds
  • This offers a drastic enhancement in ride comfort without compromising the driving performance

Wide Range Damping Force Adjustment Mechanism

  • The modified form of the needle jet expands the scope of damping force regulation
  • This enables HKS to take on driving across a broader selection of stages

Evolution of Bump Stop Rubber

  • The new form of bump stop rubber decreases body sway and concurrently provides a smooth ride experience that cannot be accomplished through standard hydro bump stop rubber

Low Friction Technology

  • Using cutting-edge tribology technology, HKS has achieved greater durability and lower friction than its conventional products
  • This technology enhances ride comfort and driving performance

3-Year Warranty

  • The HIPERMAX S Series boasts a more extended warranty of three years compared to the one-year period provided by conventional MAX IV GT series, which is attributed to its optimized internal components and upgraded quality

About HKS

In October 1973, two ambitious and spirited engineers had the ambition to engineer high performance engines and components that were unavailable or not developed by major Original Equipment manufacturers.

Hiroyuki Hasegawa, formerly from Yamaha Motor Company and his partner Mr.Kitagawa astutely obtained an investment from Sigma Automotive Co., Ltd–the origin of the moniker “HKS” – to start modifying fuel engine motor in a barn situated at Mount Fuji’s base located in Japan.

One year on, Mr. Hasegawa created and constructed the very first turbocharger for regular cars and has never seen his success diminish since then.

HKS made history by creating a series of unprecedented aftermarket performance products, including the first electronic turbo timer and boost controller on the market. Additionally, they were also in production for piggy-back fuel computers as well as refined fueling management tools – resulting in HKS becoming an innovator within Japan’s automotive sector.

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.
Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.
We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at with any inquiries.
