KYB Suspension Strut P/N:3340199
KYB 551124 rear left suspension strut assembly for the 2007-2017 Lexus LS460 is a high-pressure monotube gas strut that damps wheel movement at that corner of the car. This KYB strut assembly helps restore the designed control and handling of the car.
Fluid on the strut body, a bouncy ride or a clunk over bumps can mean a strut is worn. These signs alone do not prove the strut is the cause, since a worn tire can produce a similar ride complaint.
This is an OE monotube replacement for the 2007-2017 Lexus LS460, which takes one at the rear left. This listing is the rear left strut only; the rear right is a separate part ordered on its own, and the two sides are normally replaced together.
