Tein Street Basis Z Coilover Kit

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. Roads may have all sorts of surface conditions. This calls for shock absorbers with ample stroke, that operate smoothly. Thanks to this unique characteristic, you can negotiate gaps and bumps steadily on rough roads, meaning a smooth ride at low speed and stability at high speed.

STREET BASIS Z use the vehicle's original upper mounts (not included in our product kit).

• Optimal Dust Boot: guards the piston rod from damage, and keeps foreign material out of the shock absorber.
• No-Sag Spring: outstandingly sag-proof and boast extreme resiliency.
• High-Performance Damper Oil: excellent anti-foaming properties, stable viscosity in a broad temperature range, superior performance long-term.
• Rust-Proofing TEIN-Green Powder Coating: An organic solvent for minimal pollution to product a bright TEIN-green powder paint, an extremely strong and durable barrier and boost superior durability and corrosion resistance.
• Special Surface Treatment 'ZT Coating': ZT Coating surface treatment on the ride height adjustment thread is abrasion resistant against gravel/debris, and further enhances its corrosion resistance.
