Comfortable ride in all seats even at full load. Equipped with new feature Hydraulic Bump Stopper (H.B.S.).
FLEX A is equipped with new feature "Hydraulic Bump Stopper (H.B.S.)". On FLEX A, H.B.S., mounted inside the shock absorber, effectively generates damping force near and/or at full-bump, to absorb big impact smoothly. Comfortable ride in vehicles even at full occupancy will revolutionize the industry. Damping force is increased only near and/or at full-bump by narrowing the port. The relief valve installed suppresses the sudden rise in damping force, when the inner pressure exceeds the certain level. H.B.S. mechanism absorbs impact smoothly and converts accumulated power into thermal energy.
FLEX A uses twin-tube system, in pursuit of ride comfort on streets considering the use of larger tires/wheels and the lowered ride height. 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 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.
FLEX A has ever-popular 16-level damping force adjustment (comp./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.
With EDFC (Electronic Damping Force Controller) series installed, damping force can be controlled from the cockpit with ease. Stepping motors attached in place of adjustment knobs control the damping force quickly and accurately. With EDFC ACTIVE / EDFC ACTIVE PRO, damping force can be controlled automatically according to changes in G-force and/or vehicle speed, to offer very smooth and slick ride like never before. Use of EDFC turns 16-level adjustment into finer 32-level or 64-level adjustment mode o provide the optimum performance by fully utilizing the damping force adjustable range drastically widened by the use of "ADVANCE Needle".
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.
Highly durable & reliable. 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.Thoroughgoing rust-proofing. Upper mounts and lower brackets are coated with rich TEIN green powder paint.
Highly-rigid bracket & shell case. Shell case is made of high-strength steel STKM13C and solidly-constructed for firm handling and stable ride.
Smooth ride height adjustment & 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. 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.
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.
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.
TEIN offers excellent after-sales service. TEIN shock absorbers can be overhauled to restore the performance as good as new. As TEIN shock absorbers can be fully disassembled, revalving service is also available to change damping force settings to meet customer's preference.
