  • This allows HKS to engage in driving through a wider range of stages

Evolution of Bump Stop Rubber

  • The innovative bump stop rubber reduces body roll and simultaneously gives a steady ride unlike what is possible with regular hydro bump stop rubber

Low Friction Technology

  • HKS has leveraged cutting-edge tribology technology to generate products with higher durability and decreased friction compared to their traditional offerings
  • This technology improves the comfort level of riding and boosts performance

SRF (Super Response Fluid)

  • Newly developed oil exclusive to HIPERMAX R
  • Enhanced damper oil quality and viscosity
  • Improves characteristics of damping force, reaching great handling performance
  • Suppresses temperature change caused by heat

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.
