Premium Construction:

• No-Sag springs cold formed with SAE9254 steel (minimum tensile strength 200 kgf/mm2)
• Highly durable powder coating that does not peel or flake

• High-performance damper oil maintains stable viscosity in broad temperature range
• Made in Japan under strict quality control standards

The shortened shell case design provides optimum damper stroke at lower than standard vehicle ride height, ensuring plenty of shock travel even when lowered. Uses the vehicle's original upper mounts (not included in product kit). Excellent choice for daily driving and great for weekend track use.
