Product image for illustration purposes only. Actual product may vary.

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.

After careful consideration, Tein came to the conclusion that Tein 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, Tein 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.

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.Full-length ride height adjustment system, used for FLEX Z, enables adjustment of ride height by adjusting the case length, without changing the damper stroke length and/or spring pre-load. This has the advantage that the change in ride quality is kept minimal when the height is adjusted.This system not only makes it possible to maintain good balance between the low-down appearance and ride comfort, but also provides more setting choices for sport driving as well.

• Lowers 4″ to 0.5″ Front (Adjustable)
• Lowers 1.2″ to 0.4″ Rear (Adjustable)
• Based on the above, at full height, these coilovers can get pretty close to stock height if wanted
