    • Helps keep electronic safety systems performing as designed

    Fluid leaking at the strut body, a bouncy ride or a clunk over bumps can mean this strut is worn, though a worn strut mount or a tire problem can be behind the same signs, so find the cause before you replace it.

    Frequently Asked Questions

    Does this KYB front strut assembly fit the 2011-2013 Lexus IS350?

    Yes. KYB 551127 is a front left strut that fits the 2011-2013 Lexus IS350. The right side of that axle takes its own strut.

    Is this KYB strut assembly a monotube or a twin-tube design?

    Monotube. KYB 551127 has a high-pressure monotube design with two chambers: a hydraulic piston and valve area, and a nitrogen gas area with a floating piston.

    How does the piston rod on this KYB suspension strut resist seal wear?

    The rod is ultra-smooth and triple chrome plated, which reduces seal wear. Fluid leaking can be a cause of shock failure, and this finish is aimed at that.

    What can a worn front left KYB suspension strut assembly look like?

    Fluid leaking from the strut body, a bouncy ride or a clunk over bumps can point to wear. A parked, cool vehicle lets you look for a leak; a shop can confirm the rest.

    Is number 39132 a cross-reference for this strut?

    Yes. 39132 is on the interchange list for KYB 551127, along with 39139 and 4852059305.
