KYB Suspension Strut P/N:341311
KYB 551108 rear suspension strut assembly for the 2007-2011 Lexus GS350 and other vehicles damps spring and wheel movement with a high-pressure nitrogen gas monotube design. This Gas-a-just monotube strut is an OE monotube replacement meant to restore the vehicle's original capabilities and its designed control and handling.
A leaking suspension strut assembly, a bouncy ride or slow steering response can be signs of wear. Before you replace a rear suspension strut assembly, rule out tires, springs and other suspension parts as the source, since a worn tire or another suspension part can bring on a similar ride complaint.
It fits the 2007-2011 Lexus GS350 and the 2006 Lexus GS300, with a quantity of two per car. This listing is one suspension strut assembly; the other rear side is ordered separately, and both sides are normally replaced together.

This part cross-references / interchanges with the following part numbers:
Is the KYB strut assembly 551108 the right fit for the 2007-2011 Lexus GS350?
Yes. KYB 551108 is a rear suspension strut assembly for the 2007-2011 Lexus GS350, and it also fits the 2006 Lexus GS300. Both cars take two at the rear.
Does the KYB suspension strut use nitrogen gas?
Yes. KYB 551108 is a monotube with a high-pressure nitrogen gas area and a floating piston, kept apart from the air-free hydraulic piston and valve area.
What is the piston rod like on the KYB suspension strut assembly?
The piston rod on this strut assembly is ultra-smooth and triple chrome plated, which reduces seal wear.
Does a leaking rear strut mean the KYB rear strut assembly has failed?
It can. Fluid leaking can be a cause of shock failure, and a bouncy ride or slower steering response can be other signs of wear.
Is this KYB suspension strut meant for towing and heavier wheels?
Yes. Gas-a-Just monotubes are designed for vehicles that work, tow and have larger, heavier tires and wheels.
