*Incredibly Low Price & Made in Yokohama!* FLEX Z inherits all the features and quality of STREET FLEX but the adoption of new platform allows its price to be set at amazingly low range ($800 to $1,050). FLEX Z, of course, maintains the long-favored "Made in Yokohama" quality. Ride height adjustable shock absorber, fully loaded with TEIN's comprehensive technology, is now more affordable prices than ever. Sealed Structure

*New Approach to Achieve Amazingly Low Prices* After careful consideration, we came to the conclusion that we need to establish new manufacturing systems and to develop a new product platform, in order to achieve low prices the customers demand. Until now, all TEIN dampers can be disassembled for overhaul; Now, we introduce our new "Sealed Structure" for the FLEX Z. Below is a brief description of this new production process for our FLEX Z at TEIN HQ Factory in Yokohama, Japan.

Top end of shell pipe is drawn, oil & gas are injected then the opening is completely sealed by crimping process. This "Sealed Structure" process also reduces the production time, compared to the production of existing disassembable dampers.

In addition, pursuit of efficient production system, such as use of seam welding, allows us to drastically reduce the production cost.

*Twin-Tube System for Comfortable Ride on Streets!* Considering the use of larger tires/wheels and the lowered ride height, FLEX Z uses twin-tube system, in pursuit of ride comfort on streets.

In order to maintain the ride quality on streets with rough spots here and there, a shock absorber has to have sufficient stroke, be low-frictional and move smoothly.

As an oil chamber and a gas chamber are not arranged serially in a twin-tube system, it is easy to secure enough stroke. Also, low gas pressure keeps friction low.

Its smooth stroke movement makes it possible to follow rough and bumpy road surfaces quite well, offering supple ride at low speed and stable ride at high speed.
