About the Sealed Structure

The top end of the shell pipe is narrowed, oil and gas are injected, and the whole unit is sealed by crimping the metal.

This new approach massively shortens the production process. As a result, we have succeeded in vastly cutting production cost.

Full-Length Ride Height Adjustment

Advantage: adjusting ride height has little effect on ride quality.

Tein Flex Z - Toyota MR2 SW20

In addition to combining a low down style with ride comfort, this system offers more setup options for sport driving too.

Twin-Tube

Compared to the regular mono-tube system, twin-tube attains longer strokes with a smaller repulsive force, resulting in high ride comfort.

Roads may have all sorts of surface conditions. This calls for shock absorbers with ample stroke, that operate smoothly.

Thanks to flexible strokes, you can negotiate gaps and bumps steadily on rough roads, meaning a smooth ride at low speed and stability at high speed.

Damping Force Adjustable

FLEX Z features 16-level damping force adjustment, for simultaneous adjustment of compression and rebound.

Modify ride comfort and handling according to your preference, changing the properties of the shock absorber with the adjustment dial.

The above are examples; actual settings vary according to the vehicle's circumstances.

Mount Included

An easy-to-install mount, exclusively designed for each vehicle model, is included in the product kit.
For some models which do not have mount plates, original mounts are used.

: Reinforced Rubber Upper Mount
(for Strut)

: Pillow Ball Upper Mount
(for Strut)

We have devised a suitable mount for each vehicle type.
Pillow ball upper mounts for front strut suspensions feature camber adjustment.*

* Camber Angle Adjustment:

This means changing the contact patch of the tires during cornering, by changing the angle at which the tires touch the ground.

Example of Adjustment Negative camber:

Replacement Service

For this product we offer not overhaul, but a replacement service.

Our replacement service revives your shock absorber, by replacing the main part. It allows you to buy the shock absorber itself without the exterior parts like the upper mount, lower bracket, spring, etc.

Revalving is also available!

Damping Force Modification

This entails changing damping force to suit your driving conditions or preferences, by re-arranging the shock absorbers' internal components.

Stroke Modification

This entails changing the stroking distance to suit your driving conditions or preferences, by e.g. replacing or modifying the shock absorbers' internal components.

Compatible with EDFC Series (Optional)

The EDFC Series offer easy damping force adjustment from the driver's seat.*

* Some vehicle models are not compatible

High Durability and Reliability

Optimal Dust Boot

Thanks to its smooth compression and high durability, the dust boot guards the piston rod from damage, and keeps foreign material out of the shock absorber.
(Some vehicles use their OE dust boots)

No-Sag Spring

Cold formed with SAE9254 steel (minimum tensile strength 200 kgf/mm²), our springs are outstandingly sag-proof and boast extreme resiliency.

Superior rust protection is ensured with a highly durable powder coating that does not peel or flake. Our high-quality springs can be used without worries, in any conditions.

High-Performance Damper Oil

Exhibiting a stable viscosity in a broad temperature range, the high-performance damper oil sustains smooth strokes and a reliable damping force under all kinds of circumstances. It has excellent anti-foaming properties that protect it from cavitation (bubble-forming), and is resistant to overheating, so that it works noiselessly even on rough roads. The damper oil keeps up its superior performance long-term, because it is also resistant to deterioration over time.

Rust-Proofing

TEIN-Green Powder Coating

A bright TEIN-green powder paint is used on the shock absorber's shell case. Our powder coating technique produces an extremely strong and durable barrier. No harmful organic solvents are used, for minimal pollution.

Superior durability and corrosion resistance are achieved by TEIN's patented 2-Layer, 1-Bake powder coating method, which uses 2 layers of anti-rust paint on a blasted surface.
(Japanese patent number 4347712)

Special Surface Treatment 'ZTP Coating'

Our unique special surface treatment ZTP Coating makes the paint strong against chipping by flying gravel, and further enhances its corrosion resistance.

With zero claims for stuck parts due to rust in 500,000 shock absorbers, TEIN shock absorbers are amazingly rustproof. We're confident of customer satisfaction even in coastal areas or regions with heavy snowfall.
