Does it fit both the ES350 and ES300h?

Yes. It is listed for 2013-2018 Lexus ES350 and ES300h front left applications. It is side-specific, so the right side uses a different part number.

Do I need to replace both front struts?

KYB and most shops recommend replacing struts in pairs to keep handling balanced. This part covers only the front left, so the right side is a separate purchase.

Is it a direct replacement for the factory strut?

Yes. It is engineered as an OE-style replacement with stock ride height and a stud upper mount, and it comes pre-assembled with the spring and boot.

Can I install it myself?

It is a bolt-in assembly, but the strut carries spring load and affects alignment. Most owners have a shop install it and then get an alignment.

One pre-assembled front left unit: the KYB Excel-G strut, the high-carbon steel coil spring, and the boot.

About the KYB SR4395 Suspension Strut and Coil Spring Assembly - Front Left

The KYB Strut-Plus SR4395 is a front left suspension strut and coil spring assembly for 2013-2018 Lexus ES300h and 2013-2018 Lexus ES350 models. It comes pre-assembled, so the spring and strut do not need to be transferred during installation.

The assembly includes a KYB Excel-G twin-tube, gas-charged strut with a stronger steel outer shell and application-specific damping valves. The high-carbon steel coil spring is selected to match vehicle attributes and corner weights, restoring ride height within OE specifications. It is a side-specific part, with separate left and right part numbers.

It is designed to address front-end bounce, uneven ride height at the front left corner, vague steering feel, and worn or noisy suspension components. It is engineered to work with electronic safety systems such as ESC and ABS. Verify side, position, and vehicle-specific configuration before installation.
