Refine the handling and stance of your 2013+ Lexus GS350 or GS450h RWD (Fork FLM front suspension) with the FIVE8 SS Sport coilover system. Designed for drivers who want precise ride height control and improved chassis response, this setup enhances stability while preserving the smooth, refined character of the GS platform.

The GS chassis blends luxury and performance, making it an ideal candidate for a well-balanced suspension upgrade. FIVE8 SS coilovers help reduce body movement during cornering, improve overall chassis balance, and deliver a more composed and confident driving experience compared to factory suspension components.

Each kit is engineered with durability and consistency in mind. The mono-tube damper design promotes stable damping performance and improved heat management during spirited driving. Electroplated carbon steel shock bodies help resist corrosion, while CNC-machined aluminum pistons and high strength springs support predictable suspension behavior under load.

For drivers searching for dependable Lexus GS350 or GS450h coilovers, the FIVE8 SS Sport kit delivers adjustable ride height, solid construction, and improved suspension control for both daily driving and refined street builds.
