KYB SM5665 front strut mount kit for the 2010-2015 Toyota Prius and other vehicles replaces old, hardened vibration insulators that pass noise and vibration into the car. The front bearing plates act as steering pivots and support vehicle weight.
Clunks over bumps, vibration through the front end or alignment that keeps drifting can mean worn strut mounts, but a tired strut or a loose tie-rod end may be behind them instead, so find the cause before you order.
This front strut mount kit fits the 2010-2015 Toyota Prius, the 2016-2018 Toyota Mirai and the 2012-2017 Toyota Prius v, and each of these takes two. Driving something else? Look up your own year and model in the "Vehicles it fits" section.

Does the KYB SM5665 fit the 2016-2018 Toyota Mirai?
Yes. KYB SM5665 is listed for the 2016-2018 Toyota Mirai, and that car takes two of these front strut mount kits.
Do the bearings in this suspension strut mount kit change how the steering feels?
Yes. KYB SM5665 includes mount bearings that provide smoother steering and help retain front end alignment.
Are the studs and nuts matched in this KYB strut mount kit?
Yes. The studs and nuts in this front strut mount kit are matched grade.
How can I tell if my front strut mounts are going bad?
A clunk or noise over bumps, vibration coming through the front end and alignment that drifts can all be signs of an old, hardened mount.
How does the rubber in the KYB SM5665 differ from old, hardened mounts?
Old, hardened insulators pass road bumps, noise and vibration into the car. The rubber in KYB SM5665 cushions those impacts to reduce the jarring.
