Is the KYB 7210008 worth it over a cheaper twin-tube strut?

For a GS350, yes if you want firmer, more consistent damping. The monotube design resists fade better under hard driving. A twin-tube is cheaper and softer if comfort matters more.

Do I need to replace both front struts at once?

Yes. Replacing one corner alone can upset handling and wear the new strut faster. Budget for the front-right counterpart as well.

Does it fit a GS430, GS450h or GS460?

The listing specifies the 2009–2011 GS350. Verify fitment for other GS models by part number before ordering, since the 7210008 is listed for the GS350 only.

Is this a complete strut assembly with mount and spring?

It is listed as a complete strut assembly, but confirm whether the mount, bearing and boot are included. Many KYB struts ship as the damper only.

Our take on the KYB 7210008 Front Left Gas-a-just Strut

The KYB 7210008 is a front-left replacement strut for the 2009–2011 Lexus GS350, built as a high-pressure monotube Gas-a-Just unit. Monotube gas design resists aeration under hard use, so damping stays consistent where a twin-tube can fade. It is a direct-fit replacement, not a performance coilover. At $128.40 at Amazon as of November 4, 2026, it is the lowest of three new prices and a reasonable figure for a single OEM-replacement-grade strut.
