- Complete strut and coil spring assembly: a pre-assembled front-left corner unit built on an OE-restoring KYB Excel-G strut with a stronger steel outer shell and application-specific precision-designed damping valves.
- High carbon steel coil spring: application-engineered to match the strut and help hold ride height within OE specifications without sacrificing ride quality.

- Side-specific: left and right part numbers with side-specific design and components, as the vehicle manufacturer intended.
A strut assembly handles vehicle weight, sets ride height, acts as the steering pivot and helps control stability. If a worn strut or sagging spring on your Lexus ES is the cause of a rough or drifting ride, this KYB strut plus assembly restores those components in one bolt-in corner. Among KYB complete struts it was the 2018 Best Overall Import Aftermarket Product and is a #1 recommended OE replacement choice for Asian vehicles.
