Product Description

The TEIN S.Tech Lowering Springs (Part No. SKY94-S3B00) are engineered specifically for the 2000-2005 Lexus IS300 with the JCE10L chassis and 3.0 L inline-6 engine in rear-wheel-drive configuration. These springs lower the vehicle's ride height approximately 1.3" in the front and 1.5" in the rear compared to stock, giving the IS300 a more aggressive stance and improved handling characteristics on both street and spirited driving.

Built from high-strength Chrome Vanadium SAE9254V steel and finished in TEIN's signature green powder coat for corrosion resistance, this S.Tech spring set is designed to work seamlessly with the car's original or OEM-replacement dampers. The progressive spring rate design enhances road-holding capability and reduces body roll without overly compromising ride comfort. Included silencer rubbers (on applicable applications) help minimize noise, and the package is backed by a 1-year limited warranty against excessive sag and manufacturing defects for additional peace of mind.
