Description:
Tein's Flex Z coilovers are a complete twin tube coilover kit with upper mounts and offer full-length ride height adjustment and damping force adjustment.
NEW APPROACH TO ACHIEVE LOW PRICES
FLEX Z inherits all the features and quality of STREET FLEX but the adoption of new platform allows its price to be set at AN amazingly low PRICE range. 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 than ever.
After careful consideration, TEIN came to the conclusion that they need to establish new manufacturing system and to develop a new product platform, in order to achieve low prices that customers demand. Until now, all TEIN dampers could be disassembled for overhaul; Now, they introduce their new "Sealed Structure" for the FLEX Z. 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 THE STREETS
Considering the use of larger tires/wheels and the lowered ride height, FLEX A 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 SYSTEM FOR RIDE HEIGHT ADJUSTMENT WITH MINIMAL CHANGE IN RIDE QUALITY
Full-length ride height adjustment system, used for FLEX A, 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.
DAMPING FORCE IS ADJUSTABLE
FLEX A has ever-popular 16-level damping force adjustment (compression/rebound together) feature with the use of needle valve. By turning the adjustment knob, damping force (stiffness) is adjusted linearly step by step, to change the ride and handling of the car to suit driver's needs/preferences. Use of well-reputed "ADVANCE Needle" at the needle valve for oil flow control widens damping force adjustable range to about 200% of the existing lineups. Whether it's for the handling characteristics of sport driving or for the ride quality according to numbers of passengers, finding the most desirable setting is easier than ever.
UPPER MOUNTS INCLUDED FOR EASY INSTALLATION
FLEX A kit includes upper mounts exclusively designed for each vehicle model; either reinforced rubber mounts or pillow ball mounts. Pillow ball upper mounts for front strut suspensions have camber adjustment feature. (Some vehicle models use OE mounts.)
HIGHLY DURABLE AND RELIABLE
After many years of research and study, TEIN has developed optimally-shaped dust boot made of most suitable material. Elastic & highly-durable dust boot effectively prevents damages to the piston rod and foreign substances from getting inside the shock absorber. (Some vehicle models use OE dust boots.) Final assembly of shock absorbers is done in the clean room, which is almost equivalent to operating room. Room pressure is kept under control to shut out dust & dirt and all workers entering the room must take air shower, to make sure all the assembly work is done in completely clean air, in order to maintain higher level of accuracy and reliability.
THOROUGH RUST PROOFTING
Upper mounts and lower brackets are coated with rich TEIN green powder paint. This powder paint has high coating film strength, is highly durable yet is low-pollution due to non-use of harmful solvent. After the shot blasting pre-treatment, the patented "2-layer/1-bake" treatment using anti-rust powder paint is applied for superior durability and high corrosion resistance. (Patent No. 4347712) On shell case, TEIN's self-developed one-of-a-kind "ZT Coating" is applied, for tougher protection against chipping, often caused by bounced pebbles, and rust. With zero claim rate, against adhesion, out of 500,000 dampers sold, we are confident that people living in snowfall area or near seashores would even be very satisfied.
SMOOTH RIDE HEIGHT ADJUSTMENT AND ONE-OF-A-KIND ADJUSTING WRENCH
FLEX A has adopted the new wrought aluminum spring seats and low-friction hard-resin thrust washers. These effectively reduces the friction with springs, caused during ride height adjustment, and makes it easier to adjust the ride height with pre-load on the springs. Shell cases are treated with "ZT Coating", a superlow-friction fluorine resin coating, which is tightly baked onto the surface in-house. This special coating provides superior protection against rust and high lubricity, for keeping a smooth adjustment for a long period. FLEX A kit includes one-of-a-kind user-friendly ride height adjusting wrench. It has a 12.7mm (1/2in) sq. hole for attaching spinner handle and/or torque wrench for tightening at high torque.
NO-SAG SPRINGS
Included springs are made of high-tensile steel SAE9254 (tensile strength 200kgf/mm2 or over) and cold formed for excellent resistance to sagging and for superior quality stability. Surface is powder coated for superb protection against chipping & peeling, for high durability and for superior anti-corrosion performance. High-quality spring can be used under various conditions without any worry. The most suitable shape of spring (straight or barrel-shaped) is determined for each vehicle model, to provide wide ride height adjustable range and to secure sufficient stroke without compromising ride comfort.
HIGH-SPEC DAMPER OIL
Specially-formulated high-spec oil exhibits stable viscosity characteristics at any temperature; from low to high, to allow shock absorbers to stroke smoothly and to generate damping force stably under various conditions. The oil has superior anti-foaming characteristics hence the bubble cavitation and/or thermal degradation hardly occurs, making it even suitable for tough sport driving. The oil also does not deteriorate much with age, making it possible to maintain and deliver superior performance for the long term.

Q: Do coilovers come in sets of 4?
A: Coilovers are only sold in sets of four.
Q: What do coilovers do? Why buy coilovers?
A: Coilovers allow you to lower your car and give you the ability to make adjustments in ride height. As opposed to lowering springs, which have a pre-determined, un-changing ride height, coilovers can be adjusted. This can be very valuable because if you don't know the exact ride height that will be optimal for your car, buying coilovers gives you the ability to adjust the right height and make it just right. Additionally, if you want to change your ride height based on different driving conditions, coilovers of course allow you to do so.
Q: How do you install coilovers?
A: Depending if you opt to go with the full coilover systems or the coilover sleeves, the spring and strut housing will need to be removed. Once the factory coil springs and struts are removed they can be replaced with the full coilover setup. If you're using a coilover sleeve then the factory spring will be removed from the strut setup and replaced with the coilover sleeve unit. A professional shop should install your coilovers as an alignment and corner-balancing services will need to be done at the same time the installation is completed.
Q: Why is there such a huge price difference between some coilovers? Are there different types of coilovers?
A: There are two different kinds of coilovers: full coilover systems and coilover sleeves. Coilover sleeves are just the adjustable coils themselves. If you already have shocks or struts and have a camber kit that you're content with, then just buying the coilover sleeves will be adequate. Also, if you are looking for adjustable lowering components that are inexpensive, coilover sleeves are the way to go. Full coilover systems on the other hand come with not only the adjustable coils, but also with replacement shocks or struts and with a built-in camber adjuster. Full coilover systems let you drop your car and maintain or improve ride quality, and maintain even camber. The shocks that are built into full coilovers are specifically made for lowered cars, so they will ensure a great ride quality.
Q: Will I need a camber kit after installing coilovers?
A: In some cases you will not need a camber kit, as long as your local alignment can be put back into proper specifications. If not, a camber kit will help by allowing additional adjustment beyond what your factory alignment parts are capable of.
