Quick facts

Part: KYB 551125 suspension strut assembly
Fits: 2007-2021 Toyota Tundra
Position: Front

Fluid leaking from the strut, a bouncy ride or a clunk over bumps can mean a strut is worn. Those signs alone do not prove the strut is the problem, since a loose sway bar link is another common source of clunking. Front struts are normally replaced as a pair, and this listing is a single strut.

Buyer's Q&A

Frequently Asked Questions

Does the KYB suspension strut assembly 551125 fit the 2007-2021 Toyota Tundra?

Yes. KYB 551125 is a front strut assembly made for the 2007-2021 Toyota Tundra, and that vehicle takes two of them.

What does the triple chrome plated rod on this KYB suspension strut do?

The ultra-smooth triple chrome plated piston rod on the KYB 551125 reduces seal wear. That matters because fluid leaking can be a cause of shock failure.

Is the KYB front strut assembly meant for towing or larger wheels?

Yes, this strut has additional damping for vehicles that work, tow and run larger, heavier tires and wheels.

How do I tell when a front strut like this one is worn?

Fluid visible on the strut body, a bouncy ride or a clunk over bumps can mean wear. A shop can inspect the strut to confirm.

Will the KYB 551125 strut fade from aeration?

No. The high-pressure monotube design separates the gas and oil, and the hydraulic area is air-free, so it does not fade from aeration.
