Japan Market Part
This part is listed for the Japan-market Toyota Prius Alpha (ZVW41W). TEIN also lists chassis ZVW41W in the U.S. as the Toyota Prius V, 2012-2017. U.S. Prius V owners can use the Prius V listing for this part. Check your chassis code before ordering.
The TEIN RX1 Coilover Kit for your 2014-2021 Toyota Prius Alpha S, G, S-L Selection, S-Touring Selection, G-Touring Selection FWD (ZVW41W) is a performance-oriented, full-length adjustable suspension system that strikes an excellent balance between sportiness and daily comfort. It uses a twin-tube damper design that delivers long stroke and low repulsion force, improving ride quality over uneven surfaces. A Hydraulic Bump Stopper (H.B.S.) mechanism replaces conventional bump rubbers, converting hard impacts into thermal energy to reduce harsh rebound. The kit features 16-level damping adjustment for precise tuning of compression and rebound. Ride height is fully adjustable via a threaded lower seat, allowing you to lower or raise your car while maintaining damper travel. You also get camber-adjustable lower brackets, giving fine control over alignment by rotating eccentric washers.
Mounts are included - either reinforced rubber or pillow-ball, depending on the model - tailored to each application. Built with no-sag springs (SAE9254 steel) and durable TEIN-Green powder-coated bodies, it's both durable and resistant to corrosion. The damper oil is specially formulated for high-performance use, offering stable viscosity across a wide temperature range and excellent anti-foaming properties. Plus, the RX1 is compatible with TEIN's optional EDFC electronic damping controller, letting you adjust damping from inside the car for even more tuning flexibility.
