Specifications

How it works

The Street Basis S14 kit is from the Tein Street Basis Z range. The top of each shell pipe is narrowed, oil and gas are injected, and the unit is sealed by crimping the metal, which shortens production and keeps the price down. The twin-tube design gives a longer stroke with a smaller repulsive force than a regular mono-tube damper, so the car rides gaps and bumps steadily, with a smooth ride at low speed and stability at high speed.

On the Street Basis S14 kit, ride height is set by moving the lower spring seat up or down on the threaded body, a simple layout that is easy to use. Damping is fixed, with the valving matched to the supplied springs. The kit uses the original upper mounts from the car, so check they are in good condition before fitting.

Built to last

The Street Basis S14 shell case is finished in TEIN-green powder coat, applied with a patented 2-layer, 1-bake method over a blasted surface, and the ride height thread has ZTP coating against gravel, debris and rust. The damper oil holds a stable viscosity across a broad temperature range and resists foaming, heat and deterioration over time.

Fitment

The Street Basis S14 kit fits the Nissan 200SX (S14) from 1993 to 1998, rear-wheel drive, and the North American 240SX (S14) from 1995 to 1998. A separate Street Basis kit is listed for the Nissan S13. Check the Fitments tab for your exact model before ordering the Street Basis S14 kit.
