KYB Suspension Strut and Coil Spring Assembly P/N:SR4401
KYB Suspension Strut and Coil Spring Assembly P/N:SR4401
$231.99

Get your ride height and steering feel back with the KYB strut plus SR4401, a complete strut and coil spring assembly that drops in as the front-left corner unit for the 2009-2012 Lexus ES350. A strut assembly carries vehicle weight, sets ride height, acts as the steering pivot, and contributes to vehicle stability — KYB builds this Strut-Plus around an Original Equipment (OE) Restoring strut that's engineered to help restore your car's handling and control.

  • KYB Excel-G strut: a stronger steel outer shell with application-specific, precision-designed damping valves.
  • High-carbon steel coil spring: application-engineered to match the strut and help maintain proper ride height on the Lexus ES350.
  • Pre-assembled corner unit: strut, mount and spring assembled together for professional-level installation.
  • Side-specific design: KYB uses separate left and right part numbers with side-specific components, as the vehicle manufacturer intended.

Engineered to help vehicles with electronic safety systems (ESC, ABS). As an OE supplier, KYB is the #1 recommended OE replacement choice for Asian vehicles, and the Strut-Plus is a Winner of Best Overall Import Aftermarket Product. Fits the 2009-2012 Lexus ES350 — see the Buyer's Guide tab for engine-level details.

Frequently Asked Questions

Does this KYB complete struts assembly fit my car?

The SR4401 is the front-left corner unit for the 2009-2012 Lexus ES350. Confirm your year in the Buyer's Guide tab before ordering.

Is this KYB quick strut assembly fully assembled?

Yes. It ships pre-assembled with the KYB Excel-G strut, mount and spring as one corner unit, so it installs without separate spring compression.

What position does this KYB front strut assembly cover?

It is the front-left corner unit. KYB uses side-specific part numbers and components, so order the matching side for the correct position.

Should I replace both front struts at once?

Struts wear as a set, so replacing the opposing front strut at the same time helps keep handling and ride height balanced across the axle. This listing covers one front-left unit.

What makes the KYB strut plus assembly different?

It starts with an OE Restoring strut and an application-engineered high-carbon steel coil spring, developed to help restore ride height within OE specifications and original handling capabilities.
