  • Our take on the KYB 339185 Rear Left Excel-G Strut Toyota Avalon

    The KYB Excel-G 339185 is a rear-left replacement strut for the Toyota Avalon, built as an OE-grade twin-tube unit with nitrogen gas charging and hand-assembled valving. It is meant to restore the factory ride and body control rather than stiffen it, so it suits owners replacing a worn or leaking original strut. Against generic and budget struts, KYB's production-line heritage and triple-chrome piston rod are the main selling points; against performance struts, it stays closer to stock comfort. KYB is a widely trusted OE supplier, and Excel-G is its standard replacement line.

    Owners of KYB Excel-G struts generally report a ride close to the original and better body control than worn factory units. Complaints tend to center on buying singles and on the ride being firm on rough roads.

    What people mention

    • DurabilityPraisedLong-term users report the struts hold up well past typical OEM life.

    About the KYB 339185 Rear Left Excel-G Strut Toyota Avalon

    The KYB Excel-G Strut 339185 is a rear left replacement strut for the Toyota Avalon. It is made on the same production lines as original equipment, with upgraded valving and materials. It is designed to restore the ride comfort and handling the vehicle had when new.

    It has a nitrogen gas-charged twin-tube design for consistent damping. The damping valves are hand-assembled in a clean environment. The piston rod is triple chrome-plated to reduce seal wear, and the rod guide is sintered iron to help maintain alignment.

    The inner cylinders are made of seamless steel, which eliminates fluid bypass. The strut bodies and brackets are thick and rigid to reduce flex. By keeping the original handling characteristics, the strut helps electronic safety systems work as intended.

    Questions and answers

    Does this fit the rear left of a Toyota Avalon?
    Yes. The 339185 is the rear-left Excel-G strut for the Toyota Avalon. Confirm your model year and trim before ordering.
    Should I replace both rear struts at once?
    It is recommended. Replacing only one side can leave mismatched damping and uneven handling, so most shops pair it with the rear-right unit.
    Is this a performance upgrade?
    No. Excel-G is KYB's OE-replacement line, tuned for factory ride and control rather than sport stiffness.
    Does it come with a spring or mount?
    Typically it is the strut assembly only. Reuse or replace the spring, mount and hardware as needed.
    How does it compare with OEM struts?
    KYB builds on OE production lines with upgraded valving and materials, aiming for stock feel with longer service life.
