Product Description

The TEIN High.Tech Lowering Springs (Part No. SKQ74-BUB00) are engineered for select rear-wheel-drive Lexus IS models, including the 2014-2016 IS250 (GSE30L), 2014-2017 IS350 F Sport (GSE31L), and 2016-2017 IS200t (ASE30L). These springs provide a moderate drop in ride height compared to stock - approximately 0.8" at the front and 0.4" at the rear - giving the vehicle a more aggressive stance while helping to improve road-holding and reduce body roll without sacrificing everyday comfort.

Crafted from high-strength Chrome Vanadium (SAE9254V) material with a corrosion-resistant gold powder coat finish, this High.Tech set is designed to work with the car's original or OEM-replacement dampers to balance ride quality and handling. The progressive spring rate design enhances responsiveness while maintaining comfort for daily driving. Included silencer rubbers on applicable applications help minimize unwanted noise, and a 1-year limited warranty protects against excessive sag and manufacturing defects, making these springs a quality suspension upgrade for Lexus IS owners.
