What is the main benefit of the monotube design in this shock?

The monotube design helps keep the oil and gas inside the shock separate. This prevents foaming, which can lead to inconsistent damping and a less controlled ride, especially when the shock is working hard.

Does this shock absorber come with everything needed for installation?

This listing is for the rear shock absorber only. It is designed as a direct replacement for your original part, but you may need to reuse some of your vehicle's original mounting hardware or purchase new components separately.

Will this shock absorber fit my specific Lexus ES trim level?

Yes, this shock absorber is verified to fit the Base, Luxury, and Ultra Luxury trim levels for both the 2019-2025 Lexus ES300h and the 2019-2025 Lexus ES350.
