Incredibly Low Price
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.

Thread-Type Ride Height Adjustment
The ride height can be adjusted by moving the lower spring seat up or down. Characteristic of this system are its simple structure and ease of use.

Twin-Tube System
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.

High Durability and Superior Quality

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
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)

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.

Camber-Adjustable Insert-Type Strut with Off-Center Sleeve
For some vehicle models with insert-type struts, eccentric sleeves are used to enable camber angle adjustments. By rotating the sleeves, camber angle can be adjusted to either negative or positive, from the standard position.

Damping Force Adjustable
STREET ADVANCE 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.
