TEIN FLEX Z Coilovers
Incredible Value. Proven Performance.
TEIN FLEX Z offers the ideal balance between affordability, comfort, and dynamic handling — perfect for spirited street driving and weekend track use. With a sealed twin-tube design and made-in-Japan quality, FLEX Z is one of the most cost-effective coilovers on the market.
Key Features:
- Incredibly Price-Friendly: A new sealed structure and production process drastically reduce costs — giving you premium coilover performance without the premium price tag.
- Sealed Structure Design: A crimped, sealed shell with pre-filled oil and gas cuts down on manufacturing time and cost, while maintaining durability and function.
- Twin-Tube Construction: Allows for longer stroke and smoother operation over uneven surfaces. Enjoy improved ride comfort at low speeds and stability at high speeds.
- 16-Level Damping Force Adjustment: Fine-tune both compression and rebound with a simple dial. Adapt your ride for daily driving, track use, or anything in between.
- Vehicle-Specific Mounts Included: Comes with custom mounts for easy installation. Pillowball upper mounts with camber adjustment are included where applicable.
- Optional EDFC Compatibility: Ready for TEIN's EDFC series, allowing electronic in-cabin damping control (sold separately; vehicle compatibility varies).
Built to Last:
- Dust Boots: Protect the piston rod from debris and damage with high-durability boots. Some models retain OE boots.
- No-Sag Springs: Made from high-tensile SAE9254 steel, these powder-coated springs resist sagging and corrosion even under extreme use.
- High-Performance Damper Oil: Delivers consistent damping across a wide temperature range. Resists foaming, cavitation, and long-term degradation.
- TEIN-Green Powder Coating: Dual-layer anti-rust coating with patented ZTP treatment for unbeatable corrosion resistance — perfect for harsh climates.
