TEIN Street Advance Z - Adjustable damping and height.
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.
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.
Compared to the regular mono-tube system, twin-tube attains longer stroke with a smaller repulsive force, resulting in high ride comfort.
Modify ride comfort and handling according to your preference, changing the properties of the shock absorber with the adjustment dial.
