Restore front-right ride height and factory handling with the KYB Strut-Plus Suspension Strut and Coil Spring Assembly SR4394, a complete pre-assembled corner unit that bolts in as a direct-fit replacement for the 2013-2018 Lexus ES300h and 2013-2018 Lexus ES350. This is the FRONT RIGHT unit, combining strut, mount, and spring in one ready-to-install package. A strut assembly supports vehicle weight, sets ride height, serves as the steering pivot, and helps control stability, so worn units are worth replacing as a matched job.

  • Excel-G strut: built on a KYB Excel-G strut with a stronger steel outer shell and application-specific, precision-designed damping valves.
  • High carbon steel coil spring: an application-engineered spring developed around the vehicle's corner weights to help keep ride height within OE specifications without sacrificing ride quality.
  • Side-specific build: left and right part numbers use side-specific design and components, engineered and pre-assembled for professional results.
  • Safety-system aware: engineered to help vehicles equipped with electronic safety systems such as ESC and ABS.

Winner of the 2018 Best Overall Import Aftermarket Product award, and a KYB #1 recommended Original Equipment replacement choice for Asian vehicles.

Frequently Asked Questions

What vehicles does the SR4394 fit?

It is a direct-fit front-right replacement for the 2013-2018 Lexus ES300h and 2013-2018 Lexus ES350. See the Buyer's Guide tab to confirm your vehicle.

What comes in this assembly?

It is a complete corner unit: the KYB Excel-G strut, the mount, and the high carbon steel coil spring, pre-assembled and ready to install.

Which corner is this unit for?

This is the FRONT RIGHT assembly. KYB uses left and right part numbers with side-specific design and components, so order the correct side.

Should I replace both sides at once?

Struts wear as a pair, so replacing both front units together is recommended for balanced, even handling. This listing covers the front-right corner only.

Will it keep my ride height correct?

The application-engineered spring is developed around the vehicle's corner weights to help maintain ride height within OE specifications while preserving ride quality.
